Nice little game you've got there. Good job :)
I love the animations. Even if the art is pretty barebones, you did great with selling the motion of those simple frames. The animation is responsive and the controls feel pretty good. Having a little variation in the SFX from hits would go a long way towards fleshing out the audioscape. I usually have 3-5 sound effects for a given thing, put them into an array, then call a random integer between 0 and the array length, then use that as the index of the effect to play.
A+ for having a monkey in the game. Monkey OP.
Congrats on making this in just a week. Well done!
