Hello, thank you for playing! I'm glad you enjoyed the game.
I was hoping that the level design would teach the mechanics to a degree; but we should include a written tutorial at the beginning/on the game page somewhere that's more detailed. (I thought experimenting and learning the mechanics would be more fun, but can see how it would be frustrating).
Apologies for not including an end screen; this is something we should have implemented.
(Just so you know; the Special Star Level is the final level)
Also; good point about the 'Dark Theme'. I was playtesting the game on a low-brightness screen, so now I realize it may be too bright.
Thank you for leaving a review; we did upload the game before submission, but we had some bugs/stretch goals that needed sorting out.
