Understandable can't rush art. And not really asking to. But the page could be updated to reflect that. Possibly a delay due to art message might be nice and courteous. Also gym update and android free release would go to restoring good will. As most articles of your game say it is dead. I mean no insult or anything just being informative.
Easily rectified just stop paying them. If they keep going on and on then it's like an early access that doesn't go anywhere. The game is okay but super simple, gameplay wise that is. If the updates were consistent and the android was free then you'd probably earn more money as that opens up more market. Also make the versions free but maybe new tiers for custom characters, maybe? Like on patreon and make those payed versions and make the base game free, and to get more exclusive characters or suggested ones non free in the exclusive versions and charge like 10 bucks for it. You and the artists would make more money that way. And would restore more goodwill and respect from your fans. Because right now everything I read is negative. And you'll lose people that way.
