I believe this game suffers from camera issues and visual indicators. The feeling of the game is like Sisyphus pushing the boulder up hill. While checkpoints aren't necessary, a better distinction between what a platform is and what is background would've been nice. There were many times where I didn't know where to go because (especially for the bottom parts of the game) the platforms bended in too much with the background. Additionally, many parts of the game require that I take an unreasonable risk similar to that of something I would see in Kaizo Super Mario World.
If you continue to polish the game here is what I recommend:
- Fixing the camera (preventing showing the blue skybox. You could do that by creating a script which bounds the camera between coordinates)
- Making platforms (atleast on the lower level) more obviously distinct from the background
- Fairer platforms (moving platforms tracks and falling platform differentiation)
The game has a lot of potential, and I strongly encourage you to look into polishing up the game a bit more. For 48 hours though, well done!
