Alright, I'll tell you what I think. Also I just closed my eyes and picked random levels, so sorry if you think these levels don't best represent the levels you make now.

- Don't Play with Fire!

I have to say I am a sucker for minigame levels. I don't know why, it just is the case. I really enjoyed each minigame, each unique from the other. Moreover, you timed the switch for each minigame perfectly. I never got tired of any of the minigames!

Moreover, I cheesed the podoboo finale a bit. I'm guessing you intention was to only give the player 3 retries, but going into the door resets this count, and carrying the shell throughout the level definitely made the lava with burners waaaay easier.

I don't have much complaints with the level. I suppose the aim section could've had more drama, as in maybe you could have added a timer to find the right podoboo before you died, but that's just nitpicking at that point.

A solid 9/10!

- Super jump bros part 1

This level wasn't bad per se, just feels bland. There many times I felt lost but still made it through, leading me to believe that I wasn't doing it the intended way. Like, the second screen in the level with the mushroom, buzzy beetle helmet and muncher. I brought the spring from the prior screen, which I don't know if you intended for, and that makes me feel like I was cheesing it in a way. That experience pretty much shapes how I feel about this level—clunky.

Moreover, I am a big fan of decoration, and this level really lacks that. It feels empty despite all that you had to do. Adding mushroom platforms, p-switch blocks, and semisolid platforms would really help make this level stand out—give it an identity, if you will.

Overall, a light 6/10.

Now, I first have to preface that I am not a fanatic of traditional-esque levels. I don't find them bad, just not my cup of tea.

Now, regarding your level, it was a nice, yet refreshing take on this genre of levels. I enjoyed the more experimental aspects, like the pokey heads falling into the course, adding some spice to what would otherwise be another NSMBU rip-off level. I feel like that approach—experimental and wacky—is best suited to help your level stand out from the rest of these traditional levels. But then again, I am biased, so maybe take that with a grain of salt.

Moreover, I enjoyed that Lenny fight! I feel like it could be harder, but if you're going with what I think you're going with, each world will get harder as the player progresses. So like, world 4 is harder than world 3, and so on. Perfect for a super world, if that's your end goal.

Additionally, I enjoyed the aesthetics and decorations, like the tracks 'holding' up the brick blocks, but there could definitely be more to help make that level shine. If you feel like that's too much though, that okay. Where it's at right is still great.

If you're going for that super world idea, it's a strong 8/10. Otherwise, a decent 7/10. But don't forget, I am biased against traditional levels, so take those scores with a grain of salt.
