Oh, I for sure overshot on the polish, and that was mostly by choice. Sprites are too large and colorful and the frame-rate is too high for it to feel gameboyish. I just felt I could do a better job in this format than had I gone more retro, but it's a trade-off.
Metroidvania is what I was going for, but time constrainsts made me scale it down to more of proof-of-concept. Still intend to work on the game once the opportunity arises though!
