I tested it on Windows 8.1 64-bits, and it ran fine (with occasional freezing), except for the Quit-button which crashes the game.
I have a few questions though: -what specs is the game designed for? (because my computer gets very hot from it) -what is the range on the pistols? and is there some way to lock on target or aim down sights? (because I not managing to kill enemies)
I also have some other feedback/suggestions: -you should prioritize allowing saves or including checkpoints -the control scheme does not match the actual controls (e.g. left ctrl is crouch instead of sprint) -there must be a better way to seperate hanging from the ceiling and swinging from the ceiling (now you have to wait to stop swinging before you can start climbing, otherwise you let go) -the audio clip of the one bird in the first level sounds more like a man having an orgasm
My verdict: I’m impressed and I’m looking forward to more content being added :) Well done!
