Heyo! I'm glad you think it's cute, aha. I think I might know what your issue is, however. I have a Windows 10 computer and I built the game on it, so it should have Windows support theoretically. Did you download the RTP version or the non-RTP version?
i finally manage to download the game today and got around to playing it. very cute indeed! and it kinda has a hint of yume nikki for me. its a little shorrt but i still like it very much. i have been strungling to create my own tilesets and since youre able to pull it off so well, can you give me any tips?
