The jam is now over and we have an updated version available! But if you wish to play the jam version, please do take note of the following:
[There is a bug in the jam version that causes you to be unable to release your supernova after the first level if you did not die.
We found that killing yourself / dying (once) on each level will ensure the variables for your supernova will be reset properly and you can release it at 100% charge.
Don't worry, dying will only make you restart the level, but closing the game will start you back at level 1.]
