Fun tactical game, I like the vibe of it! :-)
The first boss (3rd floor) destroyed me multiple times! 😅
I had a bug where the cost for health regeneration wouldn't reset after losing the game. So I had to close the game for each retry.
Yeah this is known, unfortunately can't fix it at this point but it's for sure a valuable lesson!
I put the whole game state within globals, so whenever the player is defeated I have to manually reset these values. This must have been one that slipped through the cracks :D
Either way, glad you liked it, sorry about the difficulty curve!
