Big Iron

Controls :

Arrow Keys / WASD -> Movement
Z -> Shoot (costs stamina)
X -> Evade / Roll (costs stamina)
C -> Special (costs 1 bottle of energy)

Q -> Swap weapons (available after purchasing more weapons)

Mechanics :
1. Everytime the player shoots a bullet (excluding special) or does a roll, the stamina bar goes down.
2. The player's stamina will regenerate every second when he / she is not doing any action (shoot / roll).
3. The player may not perform any shot / roll if he / she does not have enough stamina.
4. The player may cancel their shot with roll, and vice versa. However doing so doubles the stamina consumption (indicated by the player glowing yellow).
5. To purchase an item from the shop (items with coin icons on their side), simply shoot at the item once you have enough coins.
6. The player has to obtain the key on the current stage to unlock the door and proceed to the next stage.
