Thank you so much for playing, and especially for sticking with it all the way to room 90! That really means a lot.
Your feedback about the progression is very helpful. In the next version I'm planning to rework the progression to make the game feel faster and more rewarding, especially in the later rooms. I'm also considering adding a new game mode if I manage to get it finished in time.
Thanks again for taking the time to play and leave such useful feedback!
