At this point in the countdown, we are almost done with levels that I really have a bad opinion on and find to be very generic and forgettable in of the series and those two such words come into play of what I think for Shady Oasis, IMO. Shady Oasis was extremely generic involving the most basic platforming gameplay elements taking in place of the level from the series. Nothing from playing of what Shady Oasis is made me go "wow" unlike much of other great and unique levels of such from the series.
The biggest and likely only real gameplay element that comes in place of the level is that, it's a level that gets yourself around the basics of the headbash move but, Shady Oasis falls short in compared about how really nothing stands out in of the level as other levels such as Fracture Hills and Metropolis were more fun to master the headbash move with and allow more variety taking in place of the level.
From the very most generic enemies, I have ever seen from the series to the pretty boring and lifeless Orb mini-games of the levels with you rescuing the hippos from green ooze and chasing around thieves for magic lamps, I have found Shady Oasis to be nothing more then one of the most blandest levels I have ever seen from the series.
If it wasn't for the fact that I like the catchy music in of Shady Oasis, likely I would have this level ranked lower possibly in the bottom 20 of my countdown. Not much else to say. Very boring and lifelss level, IMO.
