Which part of the jet "took a little while to get used to"?
If you played the original demo version, and you managed to beat the jet mission are you part of an elite few 😂. That was hacked together very quickly and while I thought it was a fun challenge, it seems most people found the mission impossible. I'm glad that there was enough there for somebody to figure it out.
The art style comment makes me a little nervous, because I kind of want to make the vehicle models "worse" (lower poly, roughly the same texture detail, but lower res textures (Synty textures are like, 4k, even though they're that simple)) and replace them all with my own models, but if people like the current graphics too much that might be problematic. Maybe I stick with the "Synty models but fixed" style for the vehicles. Everything else would stay the same though. The smoke, VFX, terrain, and general look of the game is representative of what a "final" version would look like.
