Shroot

Move in an infinite world to find resources needed for the tree (earth, water and light). Stand still on a resource to collect it. Aim with your mouse to kill the chainsaws coming at you and gain XP to shoot faster.

Good luck to survive in a world with scars resources.

(If you don't kill enough chainsaws, there will be too many of them in the world and your framerate may suffer from this ^^.)
