It’s great that you tried combining 2D and 3D platforming, that’s an ambitious design choice. However, 2D alone is already a strong foundation. The movement works, and the visuals are clear, which gives you a solid base to build on.
Adding 3D introduces substantial technical complexity, especially around camera systems and input design. Because it effectively means developing two distinct gameplay styles simultaneously, it can divide focus and make refinement more difficult.
From here, I’d suggest structuring the level design a bit more, for example, by adding traps, enemies, or more intentional obstacle placement to improve the flow. Clearer platforming challenges would help keep players engaged.
Overall, it’s still rough around the edges and has room to grow, but it’s a solid effort!
