Last night I struggled with getting the camera to work properly, but I still made some progress.

some spare parts laying around

I managed to make the worm able to equip and unequip things, and I also made enemies that fly around and shoot at the player. There are only two more things I have to do, both regarding enemies – they will have to drop items on death, and spawn in random distance from player, depending on their strength. Game’s hud will be a minimalistic one – in fact you can see it on above screenshot – green squares over segments fade out as equipment is damaged.
