Some notes:
- The text size in options is actually working in reverse?
- I don't think you need explanations for those options - they're pretty much self-explanatory. Maybe keep the explanations for the ones you really thing deserve them (like 'reduced motion'). Otherwise it is clutter and wasting player time
- Great effects, liked the sfx as well
- I don't hear any music atm, I guess it will come later...
- I'd prefer larger text in general. Hard to navigate and understand (it's obvious the primary target are mobile phones, but that's an even bigger reason to make it larger)
- Other than that, it really needs gradual introduction of gameplay elements. Might want to split it for the first time played or similar.
Really great work! I'd work a bit more on having things clear, maybe some work on the art. Good luck :)
