Today I got the ladybug to follow the mouse (this was shockingly fine) and made walls (also surprisingly fine, hooray for object inheritance). I squashed a bug with collision (the "ladybugs" rotate to face each other, but initially I forgot to check if this would cause a collision). So the game now looks like this:
(I definitely need to get to sprites next, haha!)
I also made some music to play in the background. I tried to get it to sound a little silly. It's actually pretty ok!

I'll count today as a success :) Mostly I have art and level design to work on now.
