Thanks MAWO, and you were right. Late in a run, bombs and magnets were dropping every few seconds, and the kills from a bomb could roll even more bombs. So the whole endgame turned into bomb, magnet, repeat.
Just pushed a fix: bombs and magnets are now rare and on a cooldown, Luck no longer inflates them, and bomb kills can't chain into more bombs. They still show up a bit more often during boss fights, where they matter. The last few minutes should feel a lot tenser now.
Glad you liked the look and the sound. Thanks for playing all the way to the end!
