Will play some more...
I haven't finished playing this yet, but from what I've seen so far, I've liked it.
The game looks great, the animations were well done. It's a 3D shooter, and that alone impresses me. It really reminds me of Marathon and the like, which is great because I love those games. But I'm hoping it will get harder because the pistol has a clip of 60 bullets and unlimited ammo, so I'm only really using it. If there's no reason to use the other weapons (especially because of the pistol's EXP bonus) then there is very little reason to have them, other than to look pretty. But as I've said, I haven't played it right through yet, so we shall see.
Aiming mechanism is actually entertaining, but you can upgrade it to the point where it's almost too easy (pistol headshots ftw!). I don't have any huge problems with the controls, but they ARE kind of jumpy. Luckily it isn't too detrimental to gameplay thought, and it almost gives it a vintage feel. There is one thing though; when I play the game in the default view and try to switch weapons with my mouse, it just scrolls the screen. Which sucks, but you have an alternate method and there's not much you can do about the scrolling thing anyway, so I guess I can find no fault in you for that :P
The AI, so far, has been decent. I like how when the enemies are far away, they seem to hide behind walls as they walk toward you, but they do seem pretty dull in general. I think I've been hit once, and that was only due to their initial placement and not their AI. But like I said, not done, so maybe it gets better?
Other than making the aiming crazy easy, I really liked the level up system. It is a good way to keep things from getting stale fast, and a feature a lot of shooters would benefit from. It's also pretty straightforward and easy to use.
I think I hit everything I wanted to comment on...?
Overall, I really enjoyed it. Most games I'll play for a short time just to get a feel for them and review/vote them, but I think I'll actually finish this one. I can't remember if I can edit my reviews, but if I can I'll put some more feedback when I'm done.
Good job!
