Good job! The core mechanic is very interesting and you made quite a lot of levels. I also found it quite cool that you made a login system work in the 64px resolution, as well as getting that all setup during the limited game jam time. It was quite confusing for me at first to switch the direction after hitting the walls, just takes a bit to get used to it I guess.
Would have been cool to have a web version, it's quite easy to export from Godot (I had to use GLES2, the only problem with that was that nine patch textures aren't supported in that rendering backend, so I used a shader for it instead).
