It could use some tuning, like:
- Locking the camera view while in the Shop Menu;
- Preventing multi-tapping in the menu while holding AltFire;
- Showing how much Chain Mine and Firewall you have, the ammo limit for the current weapon;
- Maybe while in the shop have the shop background be a little transparent.
- A little description for the currently selected item in the shop would be nice, since it really makes me wonder what everything does.
