I think not being able to see my cursor made aiming pretty frustrating because of subtle differences causing a mismatch and missing my shots. Otherwise I like the concept of launching a ball and trying to connect it fast. I just think the lack of being able to see my mouse cursor ruins the whole thing. Perhaps a compromise would be a line that shows which way you're aiming?
Music is really nice though. I wish there was a way to force unlock all levels as a cheat. I found myself a bit frustrated but I do appreciate that there is a level select option.
One suggestion I might make is to have each connecting node have its theme be played in ascending notes/pitch as a form of extra juice. It is interesting that the bounce, however, does have this. I think that was pretty clever to do and I never would've thought of the bounce having ascending notes (but the goals not having it is pretty strange)
Come to think of it, the fact I didn't do this with the keys you collect in my game is also something I should have done.
I appreciate the level names too. I like level names.
I will play this more later. The lack of being able to aim properly is just a bit too frustrating for me. The game looks, sounds and runs nicely though! I do think the sound effects could use a bit more juice but damn the background music is catchyyy. Also I noticed
