Easily one of my favorite entries this jam. Gameplay, level design, sound, art — all excellent. Honestly the cute robot on the cover is what got me to click in the first place.
I put about two hours in and finished with a perfect score on every level. That said, I'm still curious about level 15: is it actually solvable with every tile placed up front? I tried for ages and kept hitting two merge points where the turn tiles didn't have enough passes to handle both flows. In the end I ran one branch first, then paused to lay down the other branch's turns. Was that the intended approach, or did I miss something?
One small thing I'd consider: the difficulty curve feels a bit flat at the start. It might be worth pulling a few of the page-2 techniques forward into the levels of page-1.
Thanks for making this — I had a genuinely great time with it. Well done!
