Thanks for the kind words, watching you play was very entertaining! I'll try to fix the little glitches you found.
The perks and characters you unlock are saved, but your ingame progress beyond the tutorial is reseted when you die. The dungeon is randomized, which means the rooms you encounter after you die will be different everytime. You also don't have to redo the tutorial after you've done it once.
I might implement a feature that allows you to keep your progress when you simply leave the game though. I'll look into it!
Looking forward to your next videos!
