Okay, so I haven't done a level review in a while. But I still know what to do. And last time nobody threw crap at me for this review style.
Pros:
Design is refreshing, especially in the generic era of 2.1. Favourite part is the ship part beginning around halfway through the level, love the wind splashes.
Gameplay is fun, especially for 2.1. Kudos for making good spider gameplay, which is something first-pagers can learn from. My favourite part in gameplay is the first ship.
The sync is good, but could be improved upon.
Music is amazing.
This level could definitely be buffed into demon form. This, in my eyes, is a pro, because it's refreshing to see a level where a v2 can be made rather easily, like many of the official levels.
Cons:
Design is a bit sparse towards the end.
Gameplay can be a bit annoying, especially at the first (and only) UFO and the 45% cube jumps, but nothing that hurts the level that much.
Sync, as said before, could be improved upon. This mostly falls in line with the song choice. While it IS an amazing song, it is rather hard to sync to a GD level IMO, so I'll give points for that.
Scoring:
Gameplay: 12/15. The gameplay is fun, even if slighly annoying in the beginning and middle parts.
Design: 8/10. A few parts are empty, but the rest is very good.
Sync: 3.5/5. Decent, but could stand to be improved.
Overall: 23.5/30 or 78.3%.
Mark: Good Level! Keep up the good work!
