Hey Neco! So glad you posted to give feedback. I'm watching your video right now, I can't wait to hear your criticism and I'll gladly comment & like your gameplay! :)
About the permadeath, I'm afraid it's a key mechanic for the game - and for all randomly generated dungeon crawlers in general. I know it's kinda frustrating but it'll make it 100 times more satisfying when you win :)
Gonna finish watching your video! Thanks so much for the visibility!
