:P Well, development really dropped when school started for me again, but now I'm committing myself to more time programming when I have the spare time. I actually successfully first completed making this game on Scratch, but it's gone now. I decided to wait until SmileBASIC's release before remaking it.
I got all of the enemies and their movement patterns/behaviours programmed in! I don't have internet on my 3DS right now though... Next I'll be adding the MetaCube power-up and the game over screen. After that, the options menu for color settings and stuff then Version 1.0 will be ready for release!
POLYGON version 1.1 will add some color effects and custom music, I hope :) Other plans include new enemies and an option for control style (circle pad or stylus, upper screen for 3D or lower screen)
