Pretty fun.
Movement feels a bit sluggish with the slow acceleration and deceleration but you get used to it. The tiny jump feels almost useless.
Strafing enemies felt like a tactic that doesn't work well at all so I resorted repeatedly shooting from behind corners which became old quick.
Level is a bit too dark in places.
Some of the rooms feel like you just shoved a bunch of enemies in there with little rhyme or reason.
