I kicked Perkeo's butt. I enjoyed your game, this kind of simplicity is very enjoyable from time to time 🙂 It felt like a mix of DQ1 with some FF4 sugar on top, and I liked the foe warning before opening certain doors, it feels very Shin Megami Tensei.
A very small detail, but it shouldn't display "Party healed" when you rest since you only control one character.
I think some chiptune music would have made the game even more coherent as a whole, but besides that, great job!
