I finished it.
It is a conflicting game, lots of pros and cons.
In the last part they actually try to be serious in a subplot of the story and well, I couldn’t care less. It ended up hurting the game.
And about the comedy part. It isn’t ‘funny’ generally speaking, or at least it is funny rarely, for me it’s more amusing/bizarre/zany style than anything else. Like Justin Roiland’s past creations it tries to shock people too much and you end up being numb to it.
I liked the art of the game, it’s a well realized cartoon setting with nearby ‘AAA’ video game graphics. Although it is clear they don’t have the budget really, and the game repeat environment too much.
For a game that is known for the unique ‘Style’, capital S, I actually think the gameplay is something more worth to talk about:
I liked the exploration side of it, getting all the chests, although ironically the part I liked more was before I got the jetpack, and I had to platform creatively around the scenario to get them, in fact I’m pretty sure I got chests like that I was supposed to get later with the jetpack, so now I feel I wasted my time and the game isn’t a good in this aspect as I believed, this device makes them trivial.
The combat has a nice quick pace about it, with decent move speed, the dash, the power slide, the hook, etc, I liked that. Alas, it never end up being something more than somewhat shallow, because you have both infinite health and infinite ammo. Add to that the the animations/gunplay doesn’t feel good enough, in comparison with the ‘big leagues’ of FPS.
As I said, it needs way too much time to give you more weapons, and despite the extra modes of the later weapons, I feel the game needed one more, judging it from a pure FPS perspective (I’m not counting the last fifth weapon you get for the final level). And well, a few more enemies would have been good, too.
In the other hand it has a good set of boss fights, perhaps the best I’ve seen in FPS in years. From one where the boss is killed in an accident at first and you fight in a trap he prepared as ‘vengance from the tomb’ to a psychodelic drug-fueled fight to bullet hell.
