I hate the websites (and people) like "Y8" & co, who steal the [FREE] creations of Itch.io devs to make money on their back, without any consent or remuneration. The DRM try to be basically a giant middle finger to all this soulless capitalistic trashbags. But any h4ck3rman can break that in 5 min I guess...
Canabalt art direction is very similar indeed. But I think the main inspiraton beside SimTower, is Mineshift, another PROCJAM (2021) entry.
