Very solid! This game has a lot of high-points; the art and sound are both really impressive (I especially love the death animation), the level design felt super varied, even with the simplistic mechanics of the first two levels, and the catlike spin you guys did on something as common as a jump was great as well!
The precision jumps, where you only had one block to land on, were very tricky, and I only managed to make it to the double checkpoint on level 2 (just before the teleporter), but that may just be me not having a good feel for the pouncing jump. Also the spikes did blend in to the background a little, but that kinda stuff is pretty understandable given the palette restriction.
Overall I'd say this is a very underrated entry, and deserves a lot more than just 5 ratings!
(also the text is also kinda difficult to read, but that might just be me lol)
