Both plain and original, i think it’s well executed

The second level is the hardest for me, I can't pass it again, sadly.
I got to the third level some days ago by extreme luck, but I wasn't able to beat it then, so I closed the game.
I'll give you a very honest review!

- Review for the jam -

Controls - Confusing at first (which is good because you vaguely described it at the beginning), but I think it hinders the gameplay too much (as mentioned above, it takes luck or a lot of time on the second level). And the random switching of speed just makes the game artificially harder. I think it is creative in some sense, but at the same time it makes me unable to see the rest of your game.
Art - Ugly, yes, but I feel like you could've made it worse. I like the mix of styles and scales, and I even noticed the shadow on the house lol, but I also felt the lack of attention to typography, which seems not intended (lazy). Overall it was almost too consistent in having the same level of badness.
Sound - It didn't really bothered me or made me unformfortable. The music is out of rythm, yeah, and the hit sound effect is kinda strange, but my suggestion/take is it'd be worse if you had more sfx throughout the game, like when you're charging the jump, when you land, when  you're flying, when you fall into a pit, etc. And the narration isn't that bad, honestly.
Creative Badness - There was no reason to include a literal grandma.
Theme - Completely follows the theme.

These were the most concerning points I found. Feel free to reply disagreeing.
But don't worry, it's not a bad score and I can also change my mind.
Good luck!
