So far, this was pretty fun! I haven't played many games from the 90s, but it seems to have the vibes!
I liked how the time mechanic works, and it's quite figure out how to get past a long gap or onto another platform. It is also (though probably unintended) quite fun to use vertical platforms to fling yourself onto the top of the walls.
I did get stuck in the second level for a bit, as I didn't know how to cross the gap between the second horizontal platform and the solid ground. I did eventually figure it out, but maybe the tutorial could have had a line of dialogue that talks about how speeding up time affects your momentum?
I also am not quite sure how to finish the second level, as I can't find the file I need to progress, though if it's the last level, that's fair.
Overall, a solid game that I would play more of if I could! The vibe and atmosphere is well done, and I like how the time mechanic is implemented, and how you don't have to wait around for platforms to complete their cycles. 3D can be hard to work with, and this is great for something done in a week!
Good luck with the jam!
