Great puzzle idea, especially with the changes of what the tiles do! I like it!
Would have been lovely if making it fullscreen would have scaled it up, as things were I struggled a bit reading the tiny text on a 4k monitor 😅 Also a suggestion (should you want to develop this further): grid based movement instead of smooth would feel better here I think, I overshot a tile a bunch of times 😬
But hooray, I did finish the mission successfully 😊
