I love the Darkest Dungeon vibe. And even if you are using AI to create the graphics, the result is good and the style is consistant, so no problem for me.
Like moroman44 suggested, using position to activate certain skill and having skills/attacks be able to aim/apply only to certain positions, like in DD would be great. But that is a huge step from where you are now. For now, I find the gameplay loop OK. It does get repetitive after a while. having more skills per character and being able to select the active ones before the run would be a good addition. Like maybe 4 active and 2 passives per character, with only 2 active and 1 passive unlocked at first, then unlocking more each few levels and being able to select 2 actives and 1 passive before starting the run.
Anyway, I like it and I will keep an eye on your progress
