I feel that the amount added warrants a second update (2 updates in 1 day!?)
Finished:
Movement
(sorted the proportions, the arms are a bit more “beefed up” :D)
Save/Loading
Trophies (awards for doing things in-game)
Weapon changing (when picking a gun already in the “inventory”, you get ammo)
Equipment changing
pausing/dying
aiming on the rocket launcher
mounting (climb over ¬¬) obstacles
To do:
custom reload animations for each gun
enemies (AI already done, perhaps a few tweaks, just remodeling/animating)
props (I’ve found a new graphic style :D)
levels (should be interesting)
story (hmm…)
Enhancements:
vehicles? 
new weapons?
A quick sidenote:
Objective? A fun experience… (not just “get it working”, as was the case with everything before post #17, partially because it pretty much works already now)
