This is one of the best SMW hacks. The level design, the music, and you get to play as Waluigi. But a couple of problems there's no Yoshi, when you get hit when fire or cape, you go back to small Mario or Waluigi. The game's not finished but I recommend it.
->At level 106, bouncing fishes are swimming in dirt because the layer 3 tide isn't prioritised. It is also strange to see other sprites such as shells dive in dirt.
->Some of the "direct map 16 tiles" have incorrect acting value. I did see water that act like a blank tile and a custom ledge that act like a cement block.
->At level 118 in the screen #0A, the mix of the red "!" blocks and the log tile is a bad cutoff.
->At level 11C, the tile #E13 doesn't seem to be something that allow a "tank" to move. Actually, I have no idea how could make a tank moving.
->At level 11D, fishbones are swiming nothing when the tide is at lower level.
->Level 56 is where there is water tiles that act like blank tiles. The diagonal animated water tiles aren't fitting with the original tile because of animation cutoff. The water that comes out from moving pipes isn't fitting well because the pipes are too short.
If you need more information or even help with the futur of this hack, I invite you to send me a private message.
Most of the levels, the design is correct, except when entering to the level 42 (second room of Larry's Keep). I don't think that the difficulty of this game is a issue.
As for now, there is some visuals that have a negative influence to this game.
Note: the magikoopa boss have some problems with the On/Off as the grinder can disapear in a weird way. I also though that you can jump on him because it as the same graphic as a normal magikoopa (this is also the same case for Larry).
