The game is really good when You Know How It works after a few minutes playing, but unfortunately It´s only half game, It´s a demo, You must go to another page to play all the levels. 3/5.
Spoiler: If You have problems with the controls and You are stuck in a place, right click, select "Advance" or "Fast Fordward" (IDK my OS language is in spanish) and the screen will become black, right click again and select "Play" and voilà! You will complete the game.
Ops! Blocekd after I started my secon campagin as a Alien female, hehe, in a mission all got stuck and I needed to reset the page. But I am having a fun with this game.
So great game man, I finished It today after played It some years ago, leaving It because I lost some battle. Today I keep going, maxing first the basic weapon and then upgrading some good extras. I used the double turn with my sniper, and focusing doing the best damage.
Take care using the faucets in both rooms, You can only use Them one time in the adventure and If You are not paying attention, You will lose a secret code in the mirrors.
The game is good, but sometimes I can´t find places to interact because They are too dark, mostly of Them in the Penny Arcade. Just too obscure to notice Them.
