Really cool game, I really had fun with it, but there was some problems with the gameplay that i got a little frustrated.
The jump sometimes doesn't work after another jump, i don't know if that was on purpose, but it takes out the dynamic of just running like hell and sometimes you have to stop walking just for the jump to work out.
There was once that it spawned a straight wall that there was no way to pass it.
And the first time i passed through the end i died because i jumped over, don't know if that was on purpose also but it's a little feature that can improve, in my opinion.
Aaaand the button to mute the sound effects and the music is not working...
Besides these things, i really had fun with the game and i think it is a wonderful gameplay idea.
Keep on the good work.
