Refreshing to see a coded game without an engine. The ball concept I have not seen yet. For what it tries to be, it executes that well. Rating on a global scale is pointless, we all know that.
I suggest, should you not know those, look at bullet hell genre and the tempest remakes for inspiration. They are basically music videos with the frantic gameplay as the video. I could imagine that ball shooter (what a pun, hilarious) like one of those. Eye candy, ear candy and splosions. Best played with a stick, I guess. Mandatory with shooting from balls (ok, I stop with the puns now). But seriously, that is arcade gaming.
Older than itch. Do not make me go on tvtropes. Please. I need sleep.
