I.. need.. better.. graphics.. :> And that's sad from someone who plays 2-4 hours of ascii games every day, haha ;) Other reviews here say that the graphics are appealing, but I say they need salt (or garlic, or pepper, or something..)
I just read some pretty hard-hitting stuff at PuppyGames.com about how indie devs don't need to waste time caring about customers because each game sale ends up earning them about ten cents, which sounds pretty true to me.. They also said they spend eons of time troubleshooting customer's broken PC (and rarely fixing their own game)..
In light of that, all I can say is that if the devs are happy with the art style then its perfect :> Not for me, but for them, and that's cool :) I guess I'd personally call the game "under-fed".. Its a great base, and it'd be one I'd play often if the art were more gritty and gory.. A lot of nice pixel-explosions (of fire or gore!) or things like lighting and muzzle flash, could be added, and more variants of the current zombies.. Also more scenery (blown up/burning cars, dead bodies, more general damage and blood splashes..), maybe some random-gen ambush situations (doors, cars or garages that can release or hide zombies).. Some character customization, even a utility for editing and recoloring the player character and zombies..
A game is worth its content, and regardless of business-related ups and downs, one fact that'll never change is: You can't stop a good game from selling.
Can't. Can not :> Terraria goes for ten bucks when not on sale, and I don't think its a game that should even go on sale :| I would have paid 30 bucks for it, easy, because its had more time and care given to it than the grand majority of my Steam games, even among AAA titles.. Tales of Maj'Eyal is another great one and its a non-animated tile-graphics game.. But those graphics have soul, and the game represented by those tiles has a blasphemous wealth of content..
Love your game, and add more love! There is such a thing as a game that never stops selling, believe it!
