Hey there, I enjoy these types of RPGs. I'm only 30 minutes in (chapter 1-2), and the fact you have voice acting makes it a stand-out already. I didn't understand a 4 GB RPG like this, but the voice acting makes it understandable. I play RPGs mostly for the combat and the ability diversity here is good already and I'm sure it will expand. The switches to open doors and disable traps is a nice touch. The only thing missing here is having a cave atmosphere that differs from the outside. Should probably be darker or dimmer. Just a note for your future games.
The systems are good. Seeing the experience bars go up at the end. Little details most games miss. Defending recovers health and AP. Enemy names in red when they're low on health. The help for people that have never played a RPG of this type or any RPG at all. I suppose one qualm I have about combat is the enemies tend to blend in with the backgrounds. Maybe a thicker outline would help with that?
