I played the demo and was immediately like "I need to support this" so I bought into early access and got the dev build.
I think you absolutely nailed the PS1 aesthetic and game feel! And the controls are pretty tight! Love the way the camera automatically rotates the way I expect. As someone who has a lot of nostalgia for Tony Hawk's Pro Skater, as well as various other extreme sports games on the PS1 and PS2, I feel this is very well executed.
I unlocked all of the levels, but the only goal I'm STILL having trouble with is wall tapping the garage door openers in the indoor park level. >:( lol I can't seem to ever jump at them from the right angle from those railings. What's the strategy there? I feel like I'm missing something and should try wall tapping off one of the other walls first.
Also I really appreciate being able to ride around those 2 blockouts of the under construction levels. More developers sharing unfinished work I feel is only a good thing for the greater community of game developers. :)
