Custom GameMaker: Studio runner port.
Supports Symbian^3 and later.

This is an early demo, it does not have touchscreen controls yet.
Due to VRAM shortage, requires repacking textures with UndertaleModTool (it supports other games too),
a dedicated tool will be made later.

Download release for your OS, open "Scripts/Resource Importers/NewTextureRepacker.csx" in text editor,
find lines with "var pageSizeWidth = 1024;" and "var pageSizeHeight = 1024;", set value to 512 in both.

Launch the tool, open data.win file, select Scripts>Resource Importers>NewTextureRepacker.csx.
After it finishes, save data.win, copy it with other game files to E:/butterscotch/ on your Symbian device.

Track porting progress in the pull request.

Built with:
Symbian SR1 SDK
ARM C/C++ Compiler, RVCT 4.0 [build 902]
ARM Linker, RVCT 4.0 [Build 821]
