Nice short game.
The bloom is a nice way to make it look nice without too much details, I might steal that for my next projects ;)
The sound effect and music are minimalist, but do add to the experience
Though I wish that the transition sound from star to star, would progress instead of being a random sound.
Or at least be random without the repetition of the same sound bite 3 times.
I also quite like the final 3 notes on completion, they are nice and simple.
I do feel that the "sacrifice" aspect is weaker though, as you don't really sacrifice much, except that you have limited energy to reach the next star. Might have been more on theme to have to leave some of your energy behind, and have to do more smaller jumps as it goes on.
I wish you a great Trijam 333 if you do participate in that one, looks like you are quite good in those 3h constrained jams :D
Thanks for that simple but nice looking game.
Have a great week.
