Love the biome variety and the different backgrounds. You’ve made a pretty big game for a game jam! I appreciate the different music and vibes of each biome too.
I was unable to get past the castle section, though I gave it quite a few tries. It felt like there were a ton of enemies and I eventually got chipped down (an extra save / reducing the number of enemies in that area might make things a bit more manageable).
There were a decent number of jumps that I felt required more precision than I expected. Early on there were a few jumps that seemed like I needed to be almost pixel-perfect, to the point where I thought I was missing an ability! I might just be bad at platformers though.
I liked the dash a lot! It felt good to be able to dash through enemies and get around quicker.
(Also an aside: extremely impressed that you got a fully-functional save/load system made. I tried this game last night and came back to it this morning to find my save still intact!)
Nice job!
