Enjoyment and Execution 4/5 each - Some jank here and there hampers enjoyment, but pretty well-executed overall. No major glitches. Some inadvertent frustration platforming but not a ton. Hard to convey everything you want to in this sort of aesthetic and I think this is case (not the only by any means) where being minimalist fed into the conveyance problem.
Sensory 3.5/5 - rounded up to 4. Music and sound design pushes this up from a 3, but the actual use of silence didn't land super much for me.
Metroidvania 4/5 - Upgrades? Check. Exploration aspect feels a little lacking?
Minimalism 5/5 - Good use of the everything which wasn't a lot, which means good minimalism.
