Pretty solid game, I enjoyed! Comprehensive speedrunning timer system is a major plus, and something I'd have loved to see more people tackle with their entries.
The player definitely feels a little unresponsive, honestly could make sense to speed the entire game up by a bit, plus maybe some tweaks to the movement; I love momentum based games, and keeping up your speed is definitely fun, but it could definitely use to feel a little more responsive, I think.
The theme is implemented in a way that feels like it shouldn't be too major, but the vibe it gives the game is really solid; Even if not much is mechanically changed by the level feeling like a loop, it definitely feels different. Bravo on that!
Overall, really solid entry! Definitely enjoyed <3
