Great game, 5/5 +Fav, and since FlyAnvil is asking for feedback in their stupid PMs, here goes (some of it was already mentioned):
- detailed list of every effect of every mission (in proper English, including a more detailed description of the ultimate aim)
- on that note, maybe something like "danger points" instead of percentages - e.g. a 25% decrease implies a reduction by a quarter when it's actually a reduction by 25 points; minor issue
- Minimap would have been nice here and there
- Melee attacks could integrate more seemlessly into combat
- Have Movement Speed start on the second level or scrap that upgrade entirely. Makes it too easy? Compensate with MOAR ZOMBIES!
- Fix a Couple of bugs with the zombies (mentioned by others)
- More challenges (bosses, big hordes, that kind of stuff) and more varied missions (I know that's vague)
- Multiplayer would be awesome, but somehow I don't really expect that of a game in this format.
Your name is Greg Doe. You are a man. You are an entrepenuer who likes computers. Your dream is to eat a turd. People describe you as being a murderer. You don't drink. You would not be described as a mean person. The one thing you have always dreamed of inventing is clever houses. You love reading DR PEPPER! You have been given a life path. If you do not agree with it, hit choose again.
some good ideas there, but overall it's very 'meh'. also, could it be that someone confused geeks with nerds? quite the faux pas, as the cheese-eating surrender monkeys would put it.
