to crysal:
no. it's not that no one can type. it's because the game is missing things that a game should always, always have. for example, a PAUSE BUTTON. once you start, you can't stop for a second.
challenge 4 is IMPOSSIBLE. If Sword dies, you have to wait until Shield dies! You can't put Shield in the middle, because then Sword can't attack either! The controls aren't that bad. The real problem is the AI . Even if you make a bot follow another bot, it keeps shooting at every enemy bot he sees.
3/5 this game is horrible for your eyes and it is WAY too short and sort of hard. Should have been like a minigame or something. Of course, all games are much easier if you beat it for the first time.
to people who need help on lvl 9.
shoot a blue portal on the ceiling where the white spot is. shoot a yellow portal right under it. go straight down into the yellow portal. you'll notice that you'll keep going and going into the portals. that is the infinite loop. Now, shoot a blue portal next to the yellow while you're falling. Then, you should be able to make a high enough jump to get you over the wall. Now do what you did in level 6. You win the level!
