Koya Rift is an action-packed platform shooter that is built around circular, adaptive gameplay that emphasizes replay value by challenging the player with procedural content tuned to their skill level. In Koya Rift, the player must enter a hostile planet and destroy an alien race so the planet can be colonized. Each game, the player is dropped off at the surface and must venture into procedurally generated caves, earning upgrades and buying units as he goes along. The difficulty adjusts precisely to the skill of the player over time, providing them with a consistent challenge. The goal of the game is to provide a challenging, yet casual experience that’s easy to pick up and put down.

A game of Koya Rift is pretty straightforward – you find yourself above ground standing in front of one of the delivery pods from the mercenary mothership. Your minimap hides the area below ground – and you have no idea what awaits you. The terrain of each level is procedurally generated (meaning it uses advanced algorithms to make itself different every time, providing nearly endless possibilities). Below ground lies a web of tunnels and caverns that is different every single time you play. It’s impossible to know what awaits you behind every corner. Procedural generation isn't just in the level – all of your enemies will seem different too. Their size, speed, color, health, damage, and weapon behavior will be unique for each one you fight. Your own weapons are generated the same way – the Lances you bring along with you to levels are generated out of endless possibilities. One gun may fire large, single shot energy blasts that slow down and weaken all enemies in a large radius, where another gun will shoot bursts of many bullets that curve in every direction with a waving motion, another gun that fires several shots at once but can pierce through walls and home after enemies, and another that heals and enhances your allies.

You have to venture down into the unfamiliar cave system and eliminate all of the Phantom Crystals (Where the enemy soldiers are grown). Unfortunately the Phantoms are hunting you the whole time, while their crystals evolve and grow. If you manage to destroy all the enemy crystals, you win the level.

Don’t get too proud though – if you beat it too easily the game will know and will be sure to adjust the difficulty for next time. Game difficulty in Koya Rift is complex – it’s not a simple modification to the amount of health you have, and it isn't a simple easy-normal-hard scale. Difficulty is a very precise unit of measurement that expands near-infinitely in either direction in this game. If you beat your last couple of levels easily it will slightly increase, if you keep getting beaten down without a fight it will decrease to help you out. Difficulty adjustments affect almost everything in game – from the reaction speed of the Phantoms, to the speed at which they grow and evolve, to the cost of your allies, the experience they need to level up, the accuracy, size, fire rate, and density of your energy weapons, the rate of health recovery, the effects of special weapons, the size of the levels you play on, the health and damage of your enemies, the speed and fragility of your allies, the cash value of killing an opponent, the swiftness and force of enemy attacks, and even more. There are so many values that change, and when they do change, they change with such subtlety that you will not be able to pick out exactly why this next game seems like more of a challenge for you than last, or why you’re finally able to beat that one level that you were stuck on for so long.

These items combine to create an excellent formula for expandable gameplay – in the end you have a game that you can always come back to and find something different, and always be challenged regardless of your ability.

Pros:-Weapon selection Changes after each Level-Optics is acceptable Cons:-Campaign is only unlocked after battle mode (Why?)-Very repetitive-No Gamepad Support-Very Long waiting times-No Animations available-No opponent Variations- Price/Performance-Annoying loop "Music"-Short Game time-Bugs and Game Crashes-No Story Conclusion: Except pure Boredom you can't get in this Game. Unlistless Design and lack of Gameplay make for another Inconsequential Game.

Description: Indie platformer in which we will play for a flying robot who will need to destroy flying monsters similar to the muzzle of dinosaurs. The Whole game comes down to two things, the first we choose weapons, buy fellow travelers helping us destroy the monsters and we are going to destroy the monsters and crystals of their spawn which are scattered throughout the map (destroying all the Crystals gives victory), the second Action boils down to protecting our base and installing protective structures, but this idea is pretty poorly implemented and for two hours of play I encountered this only once and then during the course of the company. Before You start a company we need to pass the Arena mode several times to familiarize with the game, then when the company's lock will be removed we can pass some interesting cards and familiarize with uncomplicated plot. All the passage of the game is reduced in a couple of hours. Pros: ¥ Unusual Monsters (Here you can say that I have not met) ¥ a Large selection of weapons. ¥ There is an arena mode (that is, if the game is tightened you can play endlessly on randomly generated maps) ¥ Unusually, the character's death is realized. When We die, we start to play for one of our drones, who need to fight off the monsters fly to the body of our hero and it revives) ¥ Quite A lot of all the bonuses, simplifying the passage. Cons: ¥ Too Much of a neona (with a large number of soldiers and monsters start creepy brakes) ¥ We are not allowed to play the company until we pass the arena several times. ¥ There were cases when drones revived me in the textures of caves and then there is only one thing-restarting the level. ¥ No Russian language. ¥ No Achievements. TIP: ¥ Playing The company spend money on soldiers and upgrade one weapon that you decided to pass the game. Bottom Line: Not A masterpiece of course, but you can play. In any case, there was no aversion to the game. But when it passed, there were no thoughts about, and why still a couple of levels do not pass? Quite unusual platformer and at the same time primitive to creepy. Developers did not have to throw the game and a little finish. Whatever it was, I still recommend to familiarize with this game.
