Just pointing something out here, but...
As the name might have suggested, Giga Wrecker Alt. is a port of a game they released on steam a while back. I highly doubt this is costing them any meaningful resources.
Huh, you're right, the game was released on Steam in 2017, I'll update the OP. My point still stands, though. They complain about difficulties with the development of their big game and yet they waste time and resources (less than I thought, but still) in other projects. It's not like they could've asked to do the porting job to the dozens of small studios out there dedicated to porting stuff.
You know it deserves the GOTY.
