Would be good to have some sort of bounce effect on the walls, perhaps even something like a moment of disorientation :)
Upgrades are always good, here is a suggestion for a few: faster turning, ammo amount
Also, got a suggestion for you making the level of multiple players more fun to experience results of their play:
When there are 2 left, make a special moment:
IE: second person died, then:
the screen goes just a little bit darker, apart for a spot in the middle, with on each side on of the players, perhaps slightly zoom in, add an exciting tune like something is about to happen: and then have the two fight it out .. Sudden death moment.
It perhaps doesnt mean much, but that moment of special battle could be where the players are aiming for to end up :D
Great Ideas! thank you for your input.
faster turning i already got on my list (agility/handling).
I wrote everything down and I will check how much effort it is to create those things. I like your point about the desorientation and i'll definetly do that since it's not that hard to implement.
The sudden death moment is something about the gamer's experience which I didn't really give a lot of thoughs on. Maybie I underestimated the importance of that. I will create this with an update at the latest.
But this is something I haven't got a lot of experience with. I want to make an animation for a double kill aswell that there are short lightenings all over the screen for 1 second. I'll have to experiment with those visual effects a bit.
And I can't imagine yet how to set up a proper "coded" trigger when someone achieves a double kill .. but we'll see about that.
