To make it bigger in the browser, there's a window size setting you can change in the edit mode. Also I'm not really sure how to get past the first level D:
Its set to 720p, should it be bigger? I don’t know how it works on itch. And yeah I had to cobble together a ‘tutorial’ kind of last minute, the text around the outside is supposed to tell you what to do.
Okay, I finally figured out how to get past the first level! I had to connect the purple sides to the yellow sides. I'm not sure why the tiles snap to half a tile but I did like the puzzles in this game!
