I liked this a lot!
At first I quite struggled to understand the rules, because I couldn't tell what was happening when I clicked a square (I thought it was swapping tiles, or deleting tiles, I thought there was gravity -- I saw that when you hover over a tile, it seemingly rises up and connects with the tile above it, which misled me).
But once I got past that I enjoyed it quite a lot. It's an interesting take on the match-3 genre I haven't seen before. Here was my playthough if you wanna see my brain firing on all cylinders, ha.
