Interesting game, but I too did struggle with the level selection on my 1440p monitor, and also the settings menu was weirdly scaled showing the default unity background as a nice framing all the was around ath 1920x1080 menu. I did figure out how the game worked, however I was desperately missing a undo button. This is often not the easiest to implement, I can recommend looking into the Command Pattern though ^^ But in this current stage, making even a single mistake forces you to replay the entire level, which gets quite frustrating, leading to me trying to speed up my movement, making more msitakes etc, etc. ^^ But overall good job on the game, the mechanics worked nicely, just wish for that undo button haha!
