I really enjoyed this game. The level designs, ambience, and subtle SFX and VFX just made this game pop. And the lighting is beautiful. And just when I thought level 8 was hard, I then got to level 10's top left spike, haha! And I stopped there.
I have to to admit I sat on the first screen for a while expecting to load to the next scene, then realised that I had to navigate to the hole. It took a bit to get use the the controls. The right/left controls are very sensitvie or maybe i'm heavy handed, but I can see how that fits in the game mechanics.
Guiding the character through the 3D overlay maze was a bit tough in a couple instances. It was hard to judge some gaps and I found myself almost skewered a couple times ony to realise the spike wasn't in the background.
Maybe add a protection bubble for level 8 and 10. And maybe the square could be a slow time for environment, I found myself avoiding that buff otherwise.
Overall a great tidy game! I can see this on mobile or even console, or at least with a console controller.
