well..
First of all I have to say that this game shows a bunch of great Ideas but in my opnion they weren't as good machined as they sound.
I mean 3D graphics, shooting jesus (maye it's just a good Idead for me because I'm atheistic), blowback ( for me the blowback was annoying but I think it just added a littlt bit realistic flair into this game) and of course every tipe of Madness figure.
I don't think if it lived up to your expectations...
But if I heared this fabolous Ideas I would expect a great game ( and if I look at yours it seems to me like you didn't finish it because of lack of time)...
Advancements would be first of all a story-line, other weapons ( with higher rate of fire or less blowback for example), maybe a Boss or two, and wouldn't it be nice to have those trees also in the area you can move... so you could hide behind them?
I know that it would be difficult to make a game ike this but I am sure (just by the things I have seen in this game) that you would be able to make a game like this..
4/5 points for graphic
1/2 for gameplay
2/3 for originality
+1 extra point for the things we can hopefully expect from you...
