I like the idea and the aesthetic of it, and, it is good for a first upload. However, some suggestions:
Things to work on:
- Find a way to kinda polish it up a bit; the mechanics are nice, however, sometimes they didn't work as well and weren't as fluid, and, some of the challenge element's hitboxes felt off too.
- The font, a little pet peeve of mine so this may just be me, however, the font for "start" and "restart" were very hard to read.
- The soundtrack could've been a bit more diverse, however, I think this shouldn't be taken as a "what should've been" rather a "thing I should improve upon in the future" because resources to music can be limiting.
- Finally, the challenges themselves, they felt like they went from 0 to 100 really fast and I think it should've been a steadier pace.
- Great Aesthetic!
- Good mechanics and ideas
- Generally fun to play
Definitely has room for improvement but also a lot of potential, keep up the hard work and I think you could make a great game. :)
