Like the maps conceptually, especially the return of Basic Bounce. I don't think these are all that great right now though.
Eight Beat doesn't have much going on, but the trick panel pad in the center isn't all that fun to make it ever worth picking over something like Green Triangle to give a map that's close to compare. If you add some other stuff and didn't make the tricking gimmick take up so much of the track, then it could be pretty neat. Also the (seemingly) random sound effects could be removed so that the music can be better enjoyed. They didn't seem to have any rhyme or reason that was apparent and just disturbed the music unnecessarily.
Star Slalom is really laggy and probably needs some fixes to make it fun even in GP on my system. Even with that, there is very little room to drive on making the map very tough with little leeway on counterplay. This was only ran through once on GP Vicious like the other tracks so I missed out on taking advantage of shortcuts that might have helped me.
Basic Bounce might be really fun, but it probably should have normal springs or maybe moon panels instead of tricks so that pace doesn't break trying to take the small cuts. I think there were other problems too, but those could be from running this also really hard track for the first time.
[Spoiler] probably should have just been unlocked right away rather be required to beat in GP. I did learn how to play the track effectively from losing on it a couple times, but I didn't have much fun playing the same joke after the first time.
I think if the track design were improved, then this pack could seem less like a meme track pack. As it is now, the tracks are kind of just Hell maps or the equivalent of such as of right now. Besides that, I think the maps look distinct and could become iconic with improvement.
