i care to agree with blue but you could turn this into another game but with different affects maybe a TD if you want or a side-scroller either one you could do easily. Tower defense you could make several towers with easily enough monsters from giant worms to wyverns. make a couple old roman style towers and it makes a nice game. now for the side-scroller would be a bit more difficult, but would actually be my favorite since the multitude of characters would be nice.maybe add some new stuff like a power stomp to stun or just something creative. But overall im just trying to pitch some ideas
maybe add a sequel w/ more upgrades, and maybe like 1 or 2 upgrades which add an extra survivor?(which you can equip? I would hate to have a companion with a al when i want him with a sniper)overall great game.Also a ravager encyclopedia would be nice(a bestiary)
the game gives many blizzard references, exploding sheep, saturn sitting on the little stool outside of rangers hideout, the gameplay somewhat like warcraft3 tower game
tip:use potions when needed its weird how the game seems to know when you need more potions so use them when you need they are cheap and can save lives!
