Nice idea, but you really shouldn't have put in zombies. Setting aside the whole "zombies make a game fun" cliche and the fact that it just doesn't make much sense as we don't get a backstory of why they are there or why you are there. The zombies just make the game too difficult especially because they don't work properly, the sounds make me think i walked right past a zombie and then the zombies growl gets dimmer and suddenly it tells me i've been eaten. Played it multiple times and couldn't get to the beacon. Also some backstory would be nice.
I'm not sure how to improve this game in that regard because some people find it really easy and some people find it incredibly difficult. But I plan to use a third-party audio positioning library in my next game, which will hopefully improve things.
I will admit that the zombies were a bit of an afterthought and this whole game is a tech demo of sorts, and if I hadn't had the time limit of this also being a college project it could have ended up more polished. Originally, there was a backstory, but it sort of got pushed aside when I realised how much time I really had when I also factored in coursework, etc... I think that the next game I make will be a massive improvement on this, probably with a proper story, etc. Hopefully whenever that comes out, you'll be able to play it and let me know if it's actually better!
Anyway, thanks for the review. I appreciate people letting me know what they think, so that I can improve. It can be hard to read sometimes when it's very negative, but failing is the first step towards succeeding, right?
