Green Green Grassland
Gameplay: 7/10
This was a relatively short grassland level. It had obstacles that made it not completely linear, and had one or two bonus parts (altough I don't quite understand why there are clouds underground?).
The level was relatively easy, which is perfectly fine for the first level of a game, and it had SMB3 level length, which is ok, if you're going for that in the episode and keep it consistant.
There weren't any gimmicks in this level that enhanced gameplay or anything, but since this is the first level and it's made for inexperienced players, it's fine.
NPCs: 5/10
The enemies were the usual Goomba/Koopa/Piranha triade that you expect from a grassland level. The NPC placement was okaay most of the time, altough in some places a bit crowded, at one point there were 7 NPCs on the screen and no space for the player to dodge them. Personally, I didn't have trouble with it, but since this level is aimed towards inexperienced players, you might take another look at the NPC placement.
There were two powerups in this level, enough for the player to make it through, even an inexperienced one. Personally I thought thought the leaf was an interesting choice, since personally I would've gone with fire flowers in this kind of grassland level.
Design: 5/10
The grass tileset used in this level was very nice, but that was the only good thing this level had to offer, graphics wise. The background was way too bright and blended horribly with the tileset. Also the SMB1 NPCs and the SMW styled special blocks and the SMW pipes didn't fit in with the rest of the gfx. Then at the SMW goal you used SMB3 recolored poles even tough you used the normal SMW poles at the checkpoint. I highly advise you to change up the gfx, make the background less bright and maybe replace the NPCs with SMW enemies.
The music underlined the atmosphere of the level, altough it's really overused. Nintendo themselves is already recicling the track for the third time now, and honestly it's starting to get really annoying.
Besides that, the design is good, it wasn't too linear, and the slopes and height differences made the level look natural. Well, not completely natural, but as natural as it could be expected from a Mario level.
Another little thing: At one point there is this springboard that brings you up on a platform with a block. I thought it was kinda disappointing that the block just contained multiple coins and not a 1up or a powerup, since the block beneath the springboard already contained multiple coins.
Over all, this was an okay level, altough not really outstanding, I still enjoyed playing it. 5.7/10 moved to Average.
