Really nice, both gameplay and aesthetics! The overcharging platforms are a simple way to immediately make the game interesting.
Although I must say I was puzzled why I was dying or what I was supposed to do for a moment, because my screen wasn't tall enough to fit the game, so I missed some of the UI :p
Also, the jump in difficulty from level 7 to 8 (I think) is a bit harsh, and eventually caused me to stop playing. But I'm generally terrible at things that need quick precise inputs, so take that with a grain of salt.
