Good gam but needs some rethinking?
The actual engine looks quite solid, the graphics were nice and the maps were interesting... But what was with the whole only being able to look left and right and aim only -45 to 45 degrees from where you are facing? I found it a little silly... Maybe if the Y scale of the maps were smaller or if it was a mainly hand to hand fighting styled game (like double dragon) it might make sense.
Also the whole "oh no; a fire... I need to put this out... if only I had water in gun form... Oh! An ice ray!"... I'm guessing I required a flame thrower for the ice mounds? I noticed they were impervious to grenades... I don't think a flame thrower would do much to something that grenades don't even scratch.
Sorry for seeming so cynical. I really do think it has ALOT of potential, it's just that a little rethinking would make it sooo much better.
