Visual Appeal – 3 out of 5
This level uses Tik’s conversion of the Marble Garden tileset from Sonic 3, and well, uh, it could make much better use of said tileset. The background looks decent, even if it could use layer 7 in a better way than scrolling clouds, but the sprite area does leave room for improvement.
The tileset doesn’t really allow for too much eyecandy variety, but myself I see a few creative options there and there. Anyway, aside from being a little bland, it manages to look so-so. There are no obvious tilebugs, at least.
Playability – 3 out of 5
First of all, this level is way too short. I think I was done finishing it in a bit more than 5 minutes. Some areas are a bit interesting (such as the one with float lizards and vines), and it would’ve been cool if they had been expanded.
Also, I played this level in Hard mode (as I always do), and unfortunately, it was a cakewalk. The only place where I lost a heart was the boss arena (which was done alright, but could use some more ideas). Work on the levels difficulty more next time.
Summary
- Looks decent.
- Too short
- Too easy
Overall
Well, this shows promise. Keep my advice in mind and practise making levels.
