I was really, really impressed by this one. One would have no idea what engine it was created in if not for the telling .exe. Custom graphics, music, novel mix of plugins, all lent a unique feel. The game really gave me the impression that this dev understands the engine and what it is capable of.
Combat I found great. It was challenging, but each enemy was definitely beatable with the right strategy. There were meaningful choices to maximize your accrual of AP and stars while staying alive. My chief (non)complaint is that by the time I was ready to set up my ultimate 3.5 x damage "Amazing" attack, the bosses were already about dead. There was a lot of strategy involved in responding correctly to incoming charge attacks, and messing up once and after losing battle once, I realized what I had to do in order to survive. It's hard to make a game that can create such a satisfying feeling of failing, then understanding, and this game really nailed it.
Puzzles were pretty cool too. I enjoyed buying stuff for some reason and guessing the PIN. It felt like choices had some weight to them, and there were different approaches one could make to the challenges.
I found the game surprisingly funny and well written, with just the right amount of moral ambiguity. The dialog between the two MCs was really engaging. Across pretty much any metric I think this game did great. My top pic (out of the 12 I played so far).
