This is a good hack, but has some few flaws. I don't think this hack will be featured, as it is very short, and are way below the average standard of the featured hacks.
I'll show you what i thought about each level:
1st level: The first part had some repetive level design in the start. Cutoffness man also broke into this hack, you put a pipe on a bush, which made a pixel-thin line of background. The second part was a bit hard, and i had to make some pixel-perfect jumps to find the 1up(jumping off a goomba in midair, falling off a legde). This is a good level, but could be a bit boring.
2nd level: This level was the hardest of the four.
But there is a lot of blind jumps here, and monty moles which don't make it much easier. I HAD to use savestates for the last part, which was a pain to complete. Could use a few more platforms towards the end. But i have to say, great idea to put a hidden fire flower in behind a bush! I've never seen that idea before!
3rd level: This level was a vertical one, and i like vertical levels. The first part was a bit hard, like the previous ones. It was basically platforming, with spinies and koopas everywhere. I discovered a feather too, which made it a lot easier. I found a lakitu halfway up, and with my fire flower in the item box, i shot it down. I played around with it, and skipped the last part afterwards. The last part was a freefall level, which was pretty much okay. You should remove some of the platforms, which ruined my falling and caused me to lose my cape and flower.
4th level: This level was creatively made, but also a little repetive. It had a little short time limit, which you should consider fixing. Or at least make the upper path possible to get to from the start.
