The game is pretty solid, the music and the funky style are pretty fun. The level designs are well done, making it necessary to use mechanics learned in the past in conjunction with other tricks. My suggestion is to allow restarting the phase (or next level button? Sorry I forgot it :v) by hitting enter, space or even restart automatically instead of having to use the mouse to click the button, since this is his only time we use it. The learning curve is nice too. Amazing work! Want more if you continue the development :D
