Enjoyment 4/5. Execution 3.5 rounding up to 4/5.
The execution issues and enjoyment issues always blend into each other for me. Between what I played as a beta tester and what I played now I think the enjoyment would normally be higher, but the stuff that happened with the last boss was a lot. The actual base game is pretty enjoyable on its face! Just a lot of little details added up here and the small physics glitches in the boss fight hurt it for me :/
Sensory 4/5. What's there is good and communicative, both music and sound.
Metroidvania 5/5: Multiple mobility (or in one immobility) abilities? Check!
Minimalist 5/5: Theme supported by visuals and small number of elements? Check.
Overall solid. I know there was some 'trolliness' that was more intentional and I'll have to try the alternate physics version at some point, as I imagine it's subject to fewer accidental issues and would let the intended punishing stuff shine more.
