There are not a lot of things to do, you just drives cubes (a minetest based car-driving game already exists https://content.minetest.net/packages/paramat/driftgame/).
Maybe add a lockpick to unblock cubes to have at least the feeling of stealing something. You could add the possibility to do a robbery in the building and then having mobs chasing you so you have to run away in a cube.
I hadn't heard of driftgame or driftcar before these reviews started coming in, it definitely looks cool! As Just_Visiting mentioned, this entry was partially a joke. I am awful at GTA, only like the driving, and hate running from the police. So this is my low stress version of the only good part of GTA (imo). Thanks for reviewing!
