Starting with a comparison to monkey island is risky, since it gives very specific expectations, that I don't think you've met. Besides the final line, the dialogue does not have the jokes or whimsy the series is known for. But in general it is a neat little game. The change to platformer was surprising, and the controls did not feel precise enough to make the jumps comfortable. (A useful resource for platformer specifics https://gmtk.itch.io/platformer-toolkit) A small issue with the movement is that diagonals are faster then moving straight. This can be fixed by normalizing the final movement vector before multiplying (or when moving diagonal divide speed by 0.7)
Hope you have fun with any future projects.
