Disclaimer: I may end up mentally comparing this to your awesome Omega Protocol in MVM 20.
Enjoyment 3.5/5: Bumping this to 4. Movement felt pretty good! But the hitboxes really hurt this, see in particular one below.
Execution: 3/5: Three notes here: One, there are a lot of stretches where there's really not much of anything happening in a given room.
Two, please rethink your camera angles. Sometimes the camera got moving too slowly for the good of the player.
Three, please make sure the spike and other hitboxes are more generous to the player.
The epitome of the latter two things was: Underwater + spikes + camera angles issues was not a fun combination.
Bosses were pretty serviceable for a game jam though.
Sensory 3/5: The 3d art is neat, but a bit minimal. The music is probably the sensory highlight here.
Metroidvania: 3/5: Not really much in the way of ability progression that I could see. I liked the 'turn off the lights' puzzle in one area though. Felt a bit more like nonlinear Megaman, which might sound picky, my apologies.
Relevance to Theme: 5/5: High relevance. You're literally constantly running out of time.
