Fun game, and the fact it was made entirely in Pygame is crazy cool!
- It has a clear and coherent minimalist style, from the graphics to the choice of sfx and music. The animations of the blocks flying in at the start of each level is super polished and smooth!!
- It is a good fit for the theme and the main mechanic is creative enough that I haven't seen it anywhere else.
- The reminder text does not do a good enough job of clearly explaining the mechanics. It took me until level 9 to finally figure out what the numbers meant and how to get a higher score. Same thing with the extra circles mechanic, didnt realise it was a thing until level 8. And the fact that circles can't collide with each other was never told to the player, I was very confused as to why my circles were being forced to stop expanding until I realised that fact.
- The ability to skip levels is nice, but I think there should be a reminder for that somewhere on the HUD of each level, as right now the only spot where the player is told that is on a piece of text in level 4 that no-one's gonna read...
Overall a really polished and unique experience, well done!
