In all seriousness, it is.
The start was alright, got a pistol, the spinning reload is cool, enemies come at you, whatever.
Then I killed the first big baddie and got the Ultra Machine Gun weapon. NOW that's a fun gun.
Holding down mouse to eviscerate everything in front of you, Predator 1 style, is very satisfying.
The only point I slowed down was a level or two later, when I ran out of ammo. It took me a bit to learn the blue boxes are ammo, but until I did I thought I hit a bug since I didn't have any visual indication that conveyed I was out. Perhaps highlighting the ammo counter (and adding a mouse over to remind the player that this is an ammo count) to prevent confusion.
Only other issues are minor - if I dash to the portal at the end of a level, I'll start the next one with no dash. If I take the HP+mass increase perk, I'll start the next level with some health missing (presumably the difference between my old health value and the new one from the perk). Granted I do the same for my game, it ended up feeling strange here.
I guess the randomness is also a bit weird since while the jump from pistol to Ultra gun felt great, it probably wrecked balance a bit since I was able to massacre everything with a lucky drop. Perhaps the first 2-3 levels should have a guarantee drop, like a shotgun on the first big baddie?
Either way, it was quite fun
