Today was playing around with a little bit of gameplay logic and seeing what feels okay. In particular, experimenting with room sizes and trying out diagonal shooting. There's now a tracking camera which can follow the player around a larger room.
Aside from that, making the automated build system archive versions correctly was a priority since that's something that can't really be left not working for too long. Versions are now archived under the correct names and built with the correct in-game debug string.
