Thank you so much! I'm really glad you enjoyed it, and congratulations on beating the boss! I'm honestly surprised you managed to beat it the boss room wasn't very well balanced or optimized before the deadline!
You're also right about the timer. It currently resets when you die, so that's something I'll definitely fix in a future update.
If you have any ideas on how I could improve the game or expand the chain mechanic, I'd love to hear them. Thanks again for playing and for the awesome feedback!
