I made it to 1,285. No bugs that I experienced. The music is nice, as well as the sound effects. I'm not clear on what I'm doing though. Collecting the orbs seems to create new orbs - some of which are defense, some attack, both of which seem to die on contact. I know you're working on it still, but I saw it and wanted to jump in and try it out.
But - from what I can tell... It's about getting the highest score you can, with level-up options at certain intervals(will you be making a display to show progress on that?). Currently feels like a survivors-game/hungry shark/Spore cell stage.
