YOU MADE A GAME!
Congrats! Making something like this is a big accomplishment and I hope you keep learning and creating.
A good jam game has a simple goal and a clean execution. Your game controls well and it's mostly clear what you're supposed to do. Keep that in mind and you can keep learning and improving and making cool games.
I noticed that your diagonal movement is faster than horizontal or vertical. This is a common problem when doing the standard horizontal + vertical movement in Unity. One way to try to resolve this is to add the vectors for both input axes, then normalize it, then use that new normalized vector as your movement.
Keep making games and good job :)
