The core idea behind Wheelz2 is the same as Wheelz1 – get to the finish.
It’s still in early access, but has functioning multi-player (mostly – see a video for Forsen giving an older version a go here: https://www.youtube.com/watch?v=7BAVpFVGW6Y)
Lots of levels are now focused more on speed than Trials, but there is a good selection of various types of levels.
Some levels are tiny, more like a puzzle than a course – while others can be like the 4kmx4km redwood forest above

Also – I am currently working with https://www.crowdholding.com/ and rather enjoying it.
