Still not super sure what the game could use now.
Idea wall:
- A multiplayer mode similar to Left 4 Dead would be cool, but would be an unrealistic expectation (also I'd personally never play it, but it's still a cool idea.)
- More guns?
- More complex levels?
- Levels that have a start point and an end point that gets harder as you go?
- Randomly generated levels?
- More upgrades/stats to build?
- More "zombies", maybe with location-based armor, or with weird new gimmicks, like a zombie that gets more dangerous the bigger she gets?
- A hub that we manage and upgrade?
- More types of inflation, like water inflation to slow them?
- Better or more detailed graphics?
- More outfits for everyone?
- More player appearance customization?
- More player equipment, like shoes and helmets and whatever for different stats?
- Traps we can enable, like dart walls and inflatable player decoys?
- A story mode?
- A revamped blimp boss? (I don't understand why the boss is the easiest enemy in the game, she's so harmless...?)
- Minigames / challenges to do, maybe unlocking stuff?
- Nerf the player quite a bit, but add stats to a bunch of achievements to make the player stronger and faster as they're completed?
- Different player "classes" that come with weird abilities / bonuses?
