The slippery floor is a good idea, but I think it would be great with more responsiveness and speed. Also bigger hitboxes and quicker hit animation would be fine. And though the theme was 5 min, I think is too much time.
Overall a fun experience.

Glad you enjoyed, I should really create templates for different movement types so I can implement them easier into games, as then I could have a snappier movement system. The small hitboxes are due to there collision being detected via raycasts, so I can add a few more and increase the player's range. I was also thinking of speeding the hitting animation up, and have it not stop when the player moves. I'm wondering if more content would have increase the playability, and maybe added more of a reason why the game takes 5 mins.
