I knew there was an old original game, there's even a link somewhere, but does anyone have links to this "first rework" or maybe other Nekomatic games?
		
		
	 
Collars an Collars Rebirth are the only two games Neko has worked on at the moment. I think she's mentioned wanting to do a few side projects but has been too busy with work.
Also for the questions about the original game, and why we are on Rebirth now rather than it... Long story short As I recall Neko had a team she worked with originally on the original collars, and one of the artists on that team decided to try and make some moves on her she wasn't very comfortable, and as a result of her not wanting to any of that said artist left the team and stripped every asset out of the game he ever made an made neko legally unable to use any of them...
It pretty much destroyed the original game at that point, rendered it unsalvagable for any further releases. Hence she decided to begin work on Rebirth with just herself and one other trusted friend. Said friend has since left, and now Neko is the sole dev on the project working on it between her full time job and taking care of her family. Hence the slow but steady progress.
She has mentioned many times she'd love to be able to go full time working on the game, but it's not quite possible at the moment given her current schedule and work load.
