Wrong.
A morning person I am not, so here I am at 10.39am on Sunday, still with a fair bit to get done. Time will be tight, but I have until 3am Tuesday morning to finish. Might end up being a late one Monday night, although hopefully not too late seeing as I'm up for work at 6.30 each morning.
Anyway, I spent a fair chunk of yesterday working on GUI, and general game state logic (game->menu->game) etc. I now have the scoring and upgrading system working relatively well, most of the work now is just to balance the numbers that the upgrades give you.
Also, as I hinted above, I have my girlfriend working for me as an artist, which helps a lot, because I can't draw (paper or digital) to save myself. Obligatory screenshot:
Here we go again!
