I use MX-15 Debian Jessie 32 bit. And I try to run Mindustry using Wine 1.6.2-20. Mindustry is one of very few games that not only doesn't work, but after loading this screen, no keyboard or mouse input is possible. So I have to pull the power plug to restart my computer.
I see no point why I should use 64 bit software. Because the masters want it that way? Why shouldn't a game like MINDUSTRIE work on a 25 year old computer?
