For a game made in 3 hours, nothing bad (i will even say i liked the song), and maybe you should try being solo for a possible next jam - suit your game to your abilities and be free to create your game in more time.
Seeing one entry made me feel something about making other rhythm jam, but the first got no entries, this one Just got one, maybe is time to make something else, right? Although i would like to Join a Jam of this kind when i was starting.
As you made the only entry for my jam, i will let you decide: do you think i should make rhythm jam 3? For myself, i gave up from this jam, but i have a lot of fun in making/playing rhythm games, and i can see im not the only one. Also, If i make another rhythm jam, its time should be a single week (faster event, but time pressure) or should have more time (better games, but not usual for jams)? Feel proud. Is up to you choose
