Every update. EVERY update. For some reason, each time there's an update, nearly every asset not from that update is completely ignored. This level features nearly all the enemies, bosses, and gimmicks that are rarely used as of 1.9. Also known as nearly every asset. If you see this, please try to make use of old assets (such as the ones in this level) as well as the new ones. One particular overused asset is Roll. No offense to the character, but she is used so much as the only playable character, second only to Mega Man- and it's somewhat close. Makes you wonder if the game should be renamed Roll Maker... Okay, not really, but the point still stands.

Bonus Comment:
I'm not actually gloomy or upset at all, I'm just expressing the fact that each update, only the new stuff's used in levels. Seriously, when was the last time you used Yambow, Feeber, a water besides Burst Water, Force Beam, a regular Push Block (Oh no, it started raining them...), Stone Man, or Crash Man? My point is, try to use some of the older assets in your levels, instead of only the new (or new-ish) stuff.
