Hello, thank you for the nice comment! Great score you got there.
1. If you solve a tile it will clear all tiles around it on all layers. Sometimes more tiles need to be uncovered first. But you're right, the blue tiles here seem like they should've been cleared already :D
2. When a tile is clicked it definitely shouldn't click the ones below too. Since the tiles disappear, I just made marking mines count as a reveal.
3. I'll keep that in mind ;)
After all this is still a first prototype.
Thanks for the feedback!
