Nice game! I assume you are still "a beginner" in the game development industry? For your level I think this was already a great game, you can be very proud of yourself!
Some things I noted tho: The area for the player to move is way too small in comparision to it's move speed, I'd suggest you to change one of those things. The gameplay really gets repetitive after some while, since you just replay the levels over and over again, one suggest would be to implement a random level generator.
Another thing is, that you don't emphasize the actions enough, basically you don't have enough juice in the game (yes, juice is something professional game developers use too, game devs can be weird sometimes). I'd suggest you to look into the presentation "Juice it or lose it" It's avaiable on youtube and GDVault if I remember correctly.
But one thing you've done really well is UI Design in my opinion, I really like the simplistic design of yours! Nice game for your first jam!
(Also if you don't mind, it would be cool if you play my game :D)
