So I played the first 3 levels so far.
Most of them kind of have this generic feel to it, but they're still enjoyable to play.
A lot of effort was also put in aesthetics so the levels do look great. I did kind of wish you tried more to give levels an identity based on gameplay concepts.
I also think you should have gotten someone to fix your English because I can't even understand what some of the toads want to tell me.
Also level 3 told me there's no checkpoint, yet there is one?
I do enjoy the episode so far, but for your next one, you should try getting your own style (If someone can say "oh, it's this person's level" whenever they play yours, that's not a good thing)
In level 4 you can kill monty moles using shells, which makes the level impassable. Also the checkpoint is hidden a bit too well, it can easily be missed IMO.
Also can you get rid of the friendly paratroopa in the vertical section? Its only purpose is to give the player a heartattack.
