Enjoyment: 3/5: It feels good to run and jump around; that's about it.
Execution: 2.5/5 (rounded up to 3): Seems basically functional as a platformer, but it also feels like a situation with some things missing. I didn't get any feedback on enemies getting hit (although the player at least has the health bar!) Controls were good. I wasn't sure when I'd reached the end; for me the game went to a black screen after the group-fight against the drill enemies.
Sensory 2/5: The music was fine; there wasn't really any sound besides that. The theming felt a bit cobbled together; the running stick-man is definitely the highlight here and (this is one's man's opinion and take it as feedback, not Gospel) the whole aesthetic would probably be improved by going fuller into stick-figure, well, shapes and figures.
Metroidvania 3/5: It feels almost too sparse; there is one mobility ability that gates your progression and it is a platformer. A little bit of a bonus here is that you did include at least two branching or not-strictly-needed paths.
Theme 4/5: I think this is pretty minimalist!
