Too bad to hear MOAM is on hold. 
It's a game most if not all msx-ers have been looking forward to. Hopefully the project will be resurrected somewhere in the future. Whether it would be MSX 1 or 2 it would be an awesome game. The stuff you made for this game I saw and heard on youtube and here is just genious. It would be real sad if it was never finished. If you need help, I'd bet many would be willing to lend a hand.

Before 2011, I never really felt like going to msx fairs and events. But the first event I went to was MRC 2k11.
So why did I decide to visit this event all of a sudden?
Half of the reason for going was, that they were going to demonstrate MOAM.
The other half of the reason for going was, that they were going to demonstrate DEVA.
Double "doh!" 
yes feel my sadness :/
Ah well I met some nice people there, who got me more involved into the msx scene with coding, more fairs, meetings and irc chat etc, so its all good 
There is a lot of great games not released and some of them are very advanced... please, don´t let us to taste the honey and after take it
The demo of MOAM that I saw time ago was impressive. I hope you find time and motivation to finish this game. You have a buyer, player, prayer... killer for this game! XD
There are more great wip games like Deva, SFII, Crisis Core, Terror Relevation, Wing Warriors, D.A.R.C, Los Templos de Fuego, Super Mario World, Ghost and Goblins, ASO ... oh man... astounding

The #msxdev Compo has an encouragement prize for games like these. People wanting to see these games finshed could donate towards the prize pot.
Your list of WIP games is impressive but sadly not even complete. I would like to add Cypher, GuruLogiChamp and Hyper Soldier Angel. When you go back into the 90s the list becomes even bigger. 
They are also epic screen 4 tiles...
You just hit the nail on the head. 
Just wait until you see the multi-colored sprites. That's one of the aspects in which the merits of using the MSX2 VDP really become clear as well.
And in screen 4, we can do even bigger and faster tile animations.
