It's an interesting take on Rogue-Likes.
It plays really well, any input that I wanted from a healer game is here. (Easy selection of allies, enemies, showing ranges of spells, shop)
Looks like a horror game, the one were you would play an abandoned MMORPG as a healer and weird and spooky stuff would happen. I hope it will get better.
Your teammates are dumb as a brick, it easy for them to get stuck on any corner, they don't attack if not damaged, when they do with such a cooldown it feels that they sometimes forget where they are and just stand there.
I really like all those upgrades, but it makes me question "Am I DPS and Healing is my side hustle?", because with different upgrades game pushes you to make damage and ignore allies.
The game has really slow stages, 15 minutes to beat felt not enough, I liked that you placed speeding boots for traversal, but it would be better to make all mazes feel more fair (easily readable corridors and rooms) and combat more quick example: 2 Goliath = 45 seconds of afk casting big heal on your tank and waiting while your whole party slowly hitting one of them.
Even when I made the map and was 13 level, I was fighting big groups at every step of the way and wasted all the time that was left.
I really liked what I played, but I hope some of the slowdowns would be addressed.
