Very cool mechanics, I enjoyed it, even though it took me a little while to get into. However, the game pauses for me whenever I try clicking the upper right tile, so I can't place that one. Is that just me?
Thanks for playing! I think it has to do with how itch.io handles button clicks on web versions. Scrolling the page a little to avoid the buttons on the top right should allow clicking without pausing. Probably should've probably made the game window a little bit smaller.
