This is really impressive considering the experience you have with unity and C#; With my second ever game jam with over a year of experience I couldn't even finish a game to submit, so really well done! The game could use some sound effects and music tho, you can try Bosca Ceoil for music (brackeys has a tutorial on how to use it) and 'bfxr' for some easy randomly generated SFX, there is a download for both programs here on itch and I would highly recommend it for future game jams!
