Nice!  Need some polishing and maybe some addition to the gameplay mechanics, the little people art is cute! 

Good art style. Great job!

Many things could be improved: the sound, the enemies difficulty, some abilities or even some other levels. Also, I would suggest changing the font to something more readable! :D

I liked the graphics and the flow of the physics, I wish the leve was bigger and other things happened as well. I enjoyed it! Well done! :) 

Great idea. I few things like Sounds, Increasing enemy difficulties would have improved this game. Overall a really good game.

You really ARE the enemy. Cool use of the challenges! It could be improved with some sound though.

A great start that could be really great with a little more work! Even just some simple sounds would go along way in increasing  the enjoyability. 

I enjoyed jumping on the NPCs.   I liked that they were coming out of a shop with an awning over the door so the player isn't able to just stand over the door to jump on them.  I also liked that the game keeps track of my score.  Great job! To add to the experience, it would be nice if I could set how I control it, for example, I prefer using arrows instead of "a" and "d".  Also another way to add to the mood is with sound effects and music 

The game is basic but still some what fun to play.

I like the idea but it would’ve been nice to have a bit more interesting gameplay. Maybe the ‘enemies’ could have a randomised speed?

Either way, Good Job!

Ok so, the concept is great I think! Maybe you could have implemented some kind of difficulty scaling, maybe enemies start getting faster / stronger after some time. But cool game nonetheless!
