This was a lot of fun! I'd love to see more levels in the future or some sort of infinite mode where the game automatically clears certain combinations to give you more room.
A couple of notes from my side:
- I think a very brief, skippable tutorial would be helpful to teach players the mechanics for color matching zones, rotating pieces, etc.
- It took me a while to realize what I though was two tiles in the "Next" queue was actually just one tile. Unless the building design in the top actually matters then I would just show the colored shape outline to limit confusion
- Additionally isn't it just displaying your current tile and not actually the next one? Even without the text I associate that zone/layout of the screen as Next queue.
- Not sure when if ever it make sense for me to overwrite previous pieces, I guess if I can put 3+ squares into the "right" color while only overwriting one square I'd be net +5 but still feels very rare.
- It would be cool if overlapping buildings on the correct color had some sort of upgrade system. Then you can increase target scores for later level.
