The slicing mechanic was really fun especially when you chain slices and move really fast. This is a really good use of the jams theme and limitation.
Most of the issues I had were addressed in other comments, but I think you should limit how many slice points the player can have because sometimes you just have to wait for your character to finish going o each one before you can do anything else.
This game was a lot of fun, I ended up playing it for waaaaaay longer than I intended to. Pretty much everything about this game was perfect.
There was one pretty big problem though. I accidentally shot a corner which got me stuck in a wall that pushed me outside of the map. This happened pretty early in my gameplay so I didn't realize that I could just respawn from the last checkpoint. I fooled around up there until I decided to just break into the next level, I got stuck at this point because I didn't learn some essential mechanics or something. This kind of ruined my experience.
