Yikes...

Okay the premise drew me in but everything else about this game is pretty bad.
The controls are either sticky or strangely slidey, (how did you do that) The mice are random and you can't defend, or attack in any way.

Its just two levels long and the sudden jerky projectile thing from your "friend" is very hard to predict especially when it forces you into these lethal mice. Lastly there are issues with collision, your character moves like a piece of chibi bread cardboard, sliding over the Rest of the game. There is next to no immersion for me to not try and look for faults and that's bad.
And no REAL story to get me invested.
Lastly the art and music are just very uninspired. With eh music lasting all of 10 seconds before it badly loops.

Might wanna figure out more of what you actually want to do with this game so to make it more fun enjoyable and interesting.
As it is, its bland, badly controlling, and too short.

One star for effort.

A nice first attempt! You should go back and edit it a bit, and add such things as:
A jumping animation, so it don't look the character is walking in air.
A intro, to describe the story.
Try to fix the collision detection a bit if you can, sometimes I got stuck in air.

Other then that, a very solid first attempt! Keep it up!

It's a pretty good game, the problem I have is with the travel. The character gets hung up on the edge of a block and can't jump until you back off a bit. Also, when the height is tight, you have to hit jump twice to get ahead. Otherwise, it's good.
