Well, I'm gonna be honest.
When I saw "Thing-Thing 4" on the front page I was like "Awesome!" and jumped to try it... That was one of the only few things 'awesome' about this game.
From Thing-Thing, on up to Thing-Thing 3, you added new things each time, and I like that, don't get me wrong. However, I've also noticed a steady increase in game difficulty which, again, is not always bad. But I think you made this specific one a bit TOO difficult. It ran alright, which surprised me, but once you start getting into the offices, it becomes a mirical if you get out without the 'Health Display' on the screen.
Which brings me to another point. I happen to like how you set up the health display in this one. It's gone a long way since a numerical representation in the first, and a bar in the other two. But it's too hard to read in my opinion. If there was some set way of reading about how much health you had, that would make that system more bearable.
The Pipe. I have to admit, this is kind of a saving grace. Enemies become stupid once you get in their Deadzone, which isn't bad. But once you're in the Deadzone, there's only one thing to do. Beat the shnikies out of them with the pipe. The problem in THAT being it takes a good ten whacks to kill one. My personal opinion is that if you're going to put a melee weapon into something where gunplay is key, like Thing-Thing, it needs to be a bit more powerful. Not one hit kill, but stronger then "Okay, I've been whacking this guy for ten minutes. When is he gonna die?" kinda weak. If not stronger, it needs to have some bonus that wouldn't make you think "Cripes, I gotta use the PIPE again. Good bye life..."
The recap at the beginning was nice, and kinda made me wonder if you plan on re-doing Thing-Thing 1 and 2 in the new graphics (Thing-Thing 3 kinda already had those graphics.)
And... is it just me, or do the enemies weapons get stronger, while yours don't? Early in the game, getting shot with the Viper was nothing. Middle-late it's almost an instant kill. You'd think if they twinked their weapons out, it would effect it when you pick it up. Nope. Still the same weapon.
Also, I thought the weapons tracked a bit slowly. The "Bounching around like a jackrabbit on crack", as Norman-Matchem so delicately put it, works, but only to a degree. The advantages of that strategy is it allows you to fire at the opponent, while his shots sail harmlessly under you. It doesn't work if the weapons track downwards slowly.
It may seem like it' bashing this. I'm not, I LOVE the Thing-Thing series, it's got lots of character and has more potential then I'd know what to do with... but Thing-Thing 4 kinda killed the whole experience for me. Honestly, I've not beaten it yet, and I don't think I'll play it again for a while, just because I'm getting angry at it. I hope you don't think I'm doing this for fun, it pains me to write this, but if it gives you a better idea of what I, and maybe others, think, then I will not have written this in vein.
I'm a very generous guy, usually, but I'm going to have to give this a six. It's good, but could be much better. Remember, it's not what you add, or how much you crank up the difficulty, it's how you make it more interesting for the player. And that's really all that's important, if you think about it.
