Very clever idea and execution!
The only problem I had (in the browser version using the Brave browser) was that after claiming the 5th tile, the game started lagging to an unplayable degree.

Yeah, it's my mistake on optimization because, I used Godot and tested it during development on PC version, and never properly checked how would it work on different stages of the game, so only in the end few hours of game Jam I have seen that it's becomes laggy at the end when too much units is on the map.
