First off, the game needs a bit of polish. The movements are a key mechanic I'd focus more on. A suggestion is more than up and down or side to side. Maybe add diagonal movement to make the levels easier to complete. If you are looking for variety in art, you could buy this art pack since it is on sale right now.

Anyways, on to what this jam is being rated on your dev logs. Since your logs were back-to-back, we didn't get to see everything you did or the journey you made during this jam. Having an early dev log and a late one would have really shown us your progress, regardless of whether you're busy. Even a little bit of improvement is great to showcase and helps motivate you to keep going through the stumped parts of game dev. I hope you can continue your game and that it comes out great!
