dDevice, you tried a little too hard making a game. A simulation/make it your own is on effect on this game, please try making another, but using your physics to allow others to make it too. In otherwords, try making a level editor. Happy Gaming! :D
Well, the immortal goblin is imprevious to attack, but is prone to flinching. Try using max units. But don't use units that make enemies fly into the air.
There's some dialoge bug like when I defeated Neko's Shop. He keeps saying what he says after that every time I go finish a level. He makes me feel guilty, as it is kinda lame. :P
