Today I created the bare bones of the last few levels, and you can now game over / win too (though both just throw an exception and crash the game at the moment as theres now victory / defeat screen to switch too). Ive been mainly discovering the things my Generation Grammar currently lacks, and covering those. Luckily the system is flexible enough that doign so is fairly simple, but still it sinks time that is currently at an extreme premium.
Tomorrow I'll be looking to flesh out the content in each level, which includes more enemies, more weapons, just generally more stuff. Also ui work. But once that lots completed (tomorrow evening fingers crossed) the game should be playable from start to finish!
