Wow, that was difficult! And also awesome and very enjoyable. The soundtrack is outstanding, and fits the aesthetics of the game perfectly. The feedback is also very good. It took me a good number of times to beat the game, since at first I was focusing in destroying everything. When I realized the game is more about evading skills, I have started to arrive consistently to the boss---a really cool boss, to be honest, and surprisingly well balanced for a jam!
In conclusion, great game :)
