Some detailed thoughs on the game:
Pros:
- The level design is excellent (apart from one map but I'll get to that): it really feels like the next step in Build level design with its complexity and continous flow. It's interesting that the first bunch of zones are the what people usually like more because sure, there's some pretty amazing atmosphere in there but oh god zone 5 and 6 play like a dream.
- The art style is amazing, nuff said.
- The weapon balance is pretty great, you do have to switch around a lot to be effective. I still feel that the ion bow should pack a bit more punch though (mainly so it would feel just a bit better).
- Soundtrack: just like everyone else said it's a great job. World Builder is a true classic, In Your Interface and Broken System are awesome but really those are just the standout tracks for me, the whole ost is great listen.
- Shelly's cool: I like this more subtle character that's not so out there, I think it feels a bit more fresh than a Duke clone would have been.
Cons:
- Oh boy, some of the enemy designs I just don't like at all, mainly the spiders and tose flying brain fucks. They are cheap and boring to fight especially because their movement and hitbox are so unreliable that you just have to use the goddamn auto aim of the revolver all the time. This is especially true for the flying brain fucks because their movement is so erratic that I regulary miss them with the shotgun so "why bother? let's just the auto aim". To make things worse the flying brain fucks make no sound, blend into the environment and are dumb as fuck so lots of times you don't even notice that you've left one alive, just when it shoots you from up close. As for the spiders: there are just too fucking much of them sometimes, it's mainly because of them why I think that the first zone is the worst one in the game.
- I really don't like Cultural Divide and it pains me to say this because there is some amazing craftsmanship in there but it just plays like crap. Most of the time you don't even know where you're getting shot at, it's full of spiders and flying brain fucks and half of it is mosquito shooting like this:
I'm sorry but I can't see shit from this on my 24 inch monitor, the ion bow has no scope and those are guys with grenade launchers. And on top of this the secrets are centered around pressing random switches without you having any idea whatsoever on what they do, I think some of that shit is timed too or you have to push stuff in sequence. It's overcomplicated, it just made me angry so I gave up and moved on. Secrets should be hard but they shouldn't be this cheap and uninteresting, just tell me what I did (in text, like in Hexen, it works!) so I know what is the next step or at least know my progress.
It's the best and worst map of the game combined: it's amazing to look at it but almost every single element of its gameplay is quite bad and it's weird because maybe the map itself has nothing to do with it and the game just needs a zoom feature, slower moving flying brain fucks with sound and less or no goddamn spiders (really, those two enemy types absolutely destroy any kind of pacing the map could have).
- The enemy AI is pretty bad overall mostly because these guys hug walls like a motherfucker. This was always a thing in Build but in IF it's worse since the AI fucks those walls so hard that it's possible that you don't even notice them because for example an enemy sprite is between a locker and a corner. I got flanked countless times by this.
- Some exotic weapon would have been cool.
Overall IF is a fantastic game with a few annoying issues and exactly one bad map.
