Really cool game! I liked the concept and the style of game. The movement was perfect for the style of game and the gun play was good. The graphics were simple and clean making the game very intuitive. I would add a ammo counter on screen though to make the limited ammo feature a bit more clear. Also the room with the spikes that moved across and you need to stay in-between felt out of place in difficulty, it felt like they should be in a precision platformer not a stickman physics ragdoll game, I would make them more forgiving / move them so they are later in the game when the player has more experience. I appreciate this is a skill issue but they felt out of place and frustrating compared to the fun challenge they could be.
Overall, good entry, I think this game has potential! Well done.
