If you can't revive your partner via "G", save, reload your game and they'll be on their feet. Yes it is time consuming, but at least its an alternative. Bump this so others will know!
Everyone complaining about no autosave: You are wrong. There is an autosave, just select "retry" after the battle. Not only does it pick up from your last save, you start with a few additional resources and bonus points you won from the last battle. This is intentional as this game is near impossible to get through without losing a few times (therefore by losing you start in a strong position). Please keep this comment bumped for the n00bs!
Things everyone should know about this game: Your army is converted to resources at the end of the battle; you don't lose them. You are expected to lose, just by playing you are given bonus points to convert into resources. This is why the market is so important. The knight is basically a special ability which you can use to repeatedly deal damage to everything on the screen (its effectively invincible), make it a priority. The tank's tower function will cause it to die fast, just let it roll over things and make it way back.
Fun short little game, normally worth a 3/5, but I really thought you put extra effort into making it humorous and I liked the "shop" option at the end.
Just... lol@everyone who claims this game is too easy. Try playing more than 10 minutes into the game before casting judgment.
I'm giving up playing now. I'm on "Oh Snap", I'm lv40, best equipment possible, and have had to try 10 times just so my mage wouldn't die in the first 10 seconds. Finally got her to last a minute until she and my dragon both lost all of their life instantly. Not fun anymore.
