I liked how you progressively unlock the soundtrack. Thats very cool. I also liked the characters. Also, if this is your first game, really great job and do not let my criticism to deter you :) It is a great feat to finish a game in 4 days and I only wanted to provide some ideas for improvement.
I felt very stupid for a long time becuase the instructions are hidden on a screenshot with very dark font and when the game launches there is no instruction and no sound. I thought the game was bugged. Next time I suggest to put instructions in the main text and even ingame.
I have few suggestions that I think might push the game a bit:
- If you make a rhytm game do not start with dead silence. I know you are unlocking parts of the song by visiting planets, but maybe put in some "space humm" or something. I thought my sound is off or something, had to double check.
- On many planets you die 1 second after spawning. Show where the character is. Maybe even let it follow the path and when the countdown starts let player continue the path. It might be good to indicate which planet is the first one(easiest), so that players are not thrown off by difficulty. Something like "<-- start here"
- there is no rhytm. I would expect there would be some kind of beat you follow when doing laps around the planets.
- it was not clear to me at first if I did the planet correctly or not. The screen looks the same when I die, just the buttons are switched.
