I like how finding items in chests and defeating enemies awards you those letters. It’s exciting to find a “Card Pack” in a chest, for example, and there’s no need to code specific effects for every item!
I found myself using the same attack a lot at the start. I know I unlock more as I defeat enemies, but I would have liked to start with 3 or 4, allowing me to pick which letters I use, and how much damage I deal.
All in all, a very cool concept : )
