Wait, so this game didn't die like, what, 150 years ago? lol - a buggy game and barely any updates. If an update does come out, then it seems the developer is adding more bugs rather than fixing them. Just my opinion.
Being serious now: Does the developer even stop and think about PLAYING (their) own game? It might help to pinpoint the bugs and everything since the "developer" knows what they "want" in the game. Being a developer is about testing your shit and pinpointing your mistakes and errors before releasing it to the public. It's not about making your player base suffer due to your misfortunes or lack of self control to find the mistakes yourself. Also, RPGM is fine when making a Final Fantasy / Chrono Trigger (a damn game with a combat system in place) type of game, but this game isn't showcasing that.
On another note: I wish them the best of luck and I truly do hope the developer will start testing their builds before submitting them publicly. It's smart to implement something into a game then test it out to see if it works. It'll even help if testers could run through it before the green light is given for a public release.
