Thanks for playing! The video was great, I noticed a few bugs that don't happen on my computer just from watching it.
The thought behind the text is that its stuff that you shouldn't need to read while in combat, so it tries to not be in the way. But I might have over done it, I'll look into it.
You were very close to running out a few times and completely ran out once. But it's something I am tweaking constantly to get right but still feel fair, it matters a bit more towards the latter half I'd say.
The shield gun is mostly a backup and utility gun, it recharges it's ammo and the alt-fire can protect from projectiles and you can use it to dig through walls if you get cornered.
Thanks!
