Such a flashed out game, so fun and addictive! Maybe change the default language to English to prevent people getting scared away during the jam/s (the interface was clear enough for me but I also understand most eastern European languages so I can imagine monolingual people giving up instantly
My only (small) criticism is that it took me quite a while to understand that the locked tiles required money since the icon was so small even on full-screen on a monitor
PS: Good luck in the jam and if you have time please rate our game!
