Great game! Your idea was really unique as I couldn't have imagined a game like this one. The visuals are simple but effective and the sounds match perfectly with the game. Try adding more types of obstacles and twisting more the ones that already exist. Try to surprise the player more.
The way you used the limitation was good as it accomplishes what it was asked for, but I think is something natural, like just one "action" button instead of two actual different actions. Sorry if I'm not good at explaining myself, please tell me if I wasn't clear. 
I think your game has really cool aspects, so keep trying with different mechanics and ideas, good job!

I really like the game, because of how simple it is... Just have to press w and solve some puzzle... What makes it more interesting is the way you put credits on top of the thermometer, and the watching the value move down slowly, it was so good to watch

I VERY much enjoyed the concept of the game! The game even though it looks empty, I see a lot of potential! I really liked the mechanics of the game! Great job!

P.S: Can you rate my game, please?

40+ COOKIES? FOR SUCH A MINI GAME?

On the right way, but the limitation wasn't used that much... You do explode, romove nails and stuff... Now that I think about it it's better. Decent game!

Pretty cool concept and art style, although I think the limitation wasn't really used

I completed the game! Really nice concept. Short but really interesting. I think the limitation was not really used because I don't think mouse counts but anyway great game!
