The art and music is nice. But i can't say i enjoyed the game. Maybe like first two levels but after that, I don't really saw a point or a motivation to continue. (i played until the game looped back to the 1st level). For a first game jam it is pretty solid and I think you should continue participating in game jams and improving yourself! I do see some potential!
P.S.: Making me walk back to the start is pure evil!
