Very consistent art. Took me a minute to make sure it was made with the art kit - that's some pretty transformative work! The jump was a bit too floaty to make bouncing off the dogs to reach higher areas feel "right". Also A and D work for movement, but W doesn't jump? You were almost there! I really dislike using the arrow keys for movement, not sure if it's because left handed or just not used to it. Keep folks like me in mind for your next project to improve accessibility - I was definitely worse at the game because I had to use the wrong hand.
The biggest gripe I have though is the spikes - they're waaay too easy to miss during play. I almost always only ever saw them after I'd hit them, and have some of the spears missing their heads and thus be "safe" meant you were looking only for tiny little white spearheads, which really don't stand out contrast-wise with the rest of the level. Insta-death traps need to be SUPER obvious during motion, and not just while you're looking at a static screen at rest not having to track all the other movement in the game and plan your jump arcs and whatnot.
Sticking points aside this was one of the more artistically cohesive platformers I've come across in this jam. Well done!
