You are correct milesman.

Okay, so to start of I would like to say that I only played the level in practise mode, because this level is way to hard for me. Because of that I will leave anything that has to do with music sync out of consideration.

So lets start with the gameplay. The gameplay made a good use of gravity switches, different gamemodes, speed changes, jump orbs and other portal stuff. and the gameplay wasnt repetitive, it was kind of cool. But there is one flaw that ruined it kinda. You had alot of objects that came in or moved at the last second, which drastically cuts your reaction time and is a bit annoying. Also, some gravity portals like at the first flying part, or speed changes are invisible. This also makes you almost doomed to die. Somethimes, there also were alot of gears that blended in too much with the decoration and were really hard to notice. If you would've made these things more clear, the gameplay would be much better. Also ther eis a bug at 14% wher you get upside down :/

The design: I kinda liked it, you had some variety in it and had a couple nice ways of decorating, but it was really messy. Somethimes the _| |_| |_ spikes (if you know what I mean) got cut off, or you could see above the design of a flying part before entering the portal for example, and overal it felt like there were some different kind of decos just put into a blender and spread out everywhere, through each other and it made a messy feeling because it was so unorganized. Som deco stood out way more than other decoration, which made it look messy too. The same goes for the block designs. I think that this just isn't your best work, if I take a look at your other levels.

So, I think this belongs to high-end decent. Mainly because the gameplay is a bit annoying and because the design is very messy. I hope this review helped
