The jumping is a bit inconsistent. You should code the game so you jump only when the spacebar is released and pressed again to avoid small sequential jumps that are ineffective
What does collecting gifts do for you? If they count towards a score, I couldn't tell. Maybe display a score based on level completion (with time bonuses maybe) and a set amount for gifts. Also, only having three lives is a bit discouraging and would probably make someone frustrated to the point where they don't want to complete the game.
I may just be nitpicking, but the distances are messed up... Ther first three planets indicate Seren should be to the left as the closest planet according to the stats on the mission select screen is Dimora. So how is Lavicus almost three times closer if it's in the opposite direction?

Thanks for the advice. The new version is updated and the sequential jumps are removed. Thanks for playing, and please try it again :)
