thanks for the extra detail. I see what you mean - we definitely leaned closer to the old school 'House of the Dead' gunplay, where you basically just shoot & reload as much as you can. There's definitely more we can do in the interplay between things like fire-rate, reload time, ammo count etc.
As for you second question - the game should look like the gifs! A grey unlit space is definitely *not* the intended experience. Sounds like somethings gone wrong.
This was just a prototype built by two people in under 3 weeks - so we haven't done a huge volume of testing on a range of machines.
Any chance you could post a screenshot of what you're seeing and your hardware specs?
