Well, this has been a while!
But hey, may as give some updates none the less. Firstly, I have some bad news.
Put simply, I was storing my latest version of the mod on an SD card which I've seemingly now misplaced. So unless I can find it easily (or my backup is up to date), it seems like some progress made be lost for this game.
However, that doesn't mean the game is cancelled. Oh no, I'm actually planning to release a new demo in the next few months or so, I just need time to finish a few more levels before doing so.
As a result of this, you may be able to find the project at the Nintendo Community Fangame Convention in October 2017:http://forum.nintendocfc.com/showthread.php?tid=544
So yeah, just letting everyone know the status of this project.
