Hey SecretPocketCat, thanks for your helpful feedback! We will work on improving the readability of our game! As for the supernova not triggering, there is a bug that causes it not to trigger if you have not died at least once on the level.
The game was supposed to only have 3 levels. However we found out that if you die once on each level and trigger your supernova all the time, there is essentially no end to the amount of levels you can play.
