Get a flying character, preferably with fire, since that has higher damage and lower cooldown than the other elements and you have basically finished the game. The demon and the fire dragon are easily the best characters. Alternatively, use a character that spawns minions. Since they usually do not fly you might have a problem getting to certain places, though. It's really interesting how many totally useless characters there are in this game (all the animals). And that number only increases once you add all the characters that have useless skills (all the ones with defensive skills except for healing). Most characters are retextures anyway. Not difference between archer A and archer B. And with the few levels the game becomes a grindy chore after a very short while. You find the character that enables you to win every level and then try to find "new" ones or the dragons, even though you are probably not even going to use them for the boss....
I wanted to ask it how it could feel emotions and why it lied to me in the first place. Sadly, it didn't understand. If it had, the illusion would have been so much more profound. The way it is now, this game was a great experience, but I had a hard time developing sympathy for the machine. It felt as if it had been programmed to spare me of a decision between life and death, not as if it was genuinely afraid of having to spend these last few hours alone before facing its inevitable end. This could be so much more. While I was playing I was captured by the game, though, so this one is a clear 5/5. I love games that manage to draw me into the setting, even if I eventually do find something that could have gone better.
