I have found 3 different endings:
- the bad ending, when you collect all the gems.
- the sad ending, when you don't collect them, but kill 11 creatures.
- the good ending, when you don't collect any gem and kill no creature. (missing the teleport power up here).
@hayabusa125: I believe that retreat makes the units you have selected come back to your base, while fall back makes all your units come back to your base, wether you have them selected or not.
@PsycheTest: First you have to spend some skill points to unlock the second puzzle piece. Then drag the enhancing skill to the skill you want improved. The right shape of the original skill and the left shape of the enhancing skill must be the same to be able to mix them.
This game could be funnier if monsters had a way bigger stamina pool and slower stamina regen. This way you wouldn't play for 5 seconds every 5 minutes and people would enjoy it better.
Game doesn't save your progress, so if you don't want to play all the way from the beginning (including the pizza level), don't refresh the window even if you want to start a level again :(.
