First of all, I wanted to say, great tool!! I love the tile editing capabilities especially (being able to flip tiles and stuff makes tilesets much easier to make).
Wasn’t quite sure where else to put this, but when I switch to HD mode and make a new sprite and try to animate it, the second frame of the animation will still be 8x8, and I have to fix it manually in the game data. I’m not sure if the engine likes this. I also think it would be neat to be able to make the avatar 16x16 in the editor.
Thanks so much for making such an awesome hack!
