Cloud Convoy:
While the idea is neat, the graphics are nice and the amount of custom content impressive, this level really lost some of its potential fun with the controls. Design-wise it's really great, but I had a severe problem with depth here, the dropshadows helped, but weren't enough...
I liked the boss, but I had a bug where I died and defeated the boss at the same time in the pinch phase, sending me back to the checkpoint. Also, is it intentional that rings don't spawn in the pinch phase?
Quickman:
I have never played Megaman before due to my age (but I plan on doing so), so I can't make any comparisons.
The controls are very neat and I like how challenging the level design is, but, although I'm aware it's intentional because the old Megaman games were difficult too, I'm definitely not a fan of that pixel-prefect jump you have to do after the laser sequence. I ended up getting killed a lot of times there and due to time constraints wasn't able to finish the level. So I'm sorry if I missed some things, I won't rate you lower because of me failing.
Autumn Valley: The very simplistic artstyle is quite nice in my opinion. Otherwise though the level isn't really that exciting and the teleport was unnecessary.
Nothing too bad though.
Gravity Garden: Wow! Visually, this is an awesome level. And there are some very nice gameplay gimmicks too. The whole concept behind this map is awesome and there really were some nice puzzle elements in this level. One question though: Was this level made for Sonic and Tails only? I had some segments where I thought I was stuck due to Knuckles' jump height, thus switching to Sonic.
Koopa Garrison:
An extremely fun and visually appealing level. Some gimmicks were stretched out a bit too much (Thwomps), but apart from that I don't see anything significantly wrong with this level. Platforming at its best.
Phantom Gadget:
Again, superb visuals, creepy atmosphere aswell as a lot of cool custom content. I'm quite happy I played as Knuckles though as I can imagine I would'nt have been able to beat that last segment with Sonic.
I thought that the turrets didn't fit into the horror theme that much though. They made me get stressed, yes, but not in a scary way.
I'm generally not that of a horror fan, so the ranking is a lot of personal preference on my side here, the level is still pretty good.
Shadow Castle:
This level was confusing, but I think that was a bit intentional too.
Some of the platforming was tedious, but you had some nice gimmicks including the Heroes one. The music didn't fit that well but I liked it very much (name please?).
I'm not sure if I was too dumb again or not, but I think some of the gravity stuff can be broken by Knuckles, be careful there.
One thing you could improve on are the visuals, they're somewhat lacking.
The level might not be as well crafted as others in the contest, but I still had lots of fun going through it.
