As of 2022, has there at least been any updates on this project?
I'm not technically the project owner (despite my support ever since I encountered this fan game myself).
For more information about this project, there's a cool Discord server associated with it that's linked in the description. It's up to you if you want to see for yourself (I won't anyhow force you).
So the whole idea of this was to make SMW styled graphics?
How about an SMW styled R.O.B.?
Spark (Balloon Fight)
A flashing 16x16 lightning ball (that can be placed anywhere, mostly encouraged airborne) that damages the player upon contact.
There are also variants where it can move too as in the original source game.
