So controlling the camera was very tricky as the cursor wasn't locked. You just end up with about a 90 degree sector you can look at. And controls overall felt kinda weird. Kinda forgot about the dash for like over half of the playtime. That seemed to be the only way to actually have some control over the character as the bounces were somewhat unruly but obviously not being able to fully control the camera ie. the dash direction either didn't really help. I ended up with some final parts being so high up the stage that I would have needed to jump from the edge but the camera refused to allow me to dash that way. Kinda infuriating.
The visuals were nice. Pretty nice 3d models which I can now appreciate a lot more after first time trying to make my own game in 3d too. Very pleasant to look at color palette too. The player character seemed a bit plain to look at. Maybe because it was all just plain white as you only saw it from behind. Really would have wanted to have some audio there too.
But a multiplier game too, dang. But a multiplier game would require some more players. Wonder if it'd work better with more players.
Oh saw you mention the camera control working on the downloadable version. Not sure if that is correct with multiple screen setup as the cursor can still leave the full screened app and deactivate it. Locking the cursor to the center of the screen (Cursor.lockState = true) would fix this and it does work on web version too.
