For those that are technically advanced, open dev tools (like Chrome dev tools or Firebug) and find div with id game_wrapper and change the left css style to 0 to fix the visibility problem. This has to be fixed on their end of course.
Play again should be triggered by space so that you'd truly only need space to play this game. It's difficult to get some achievements, and that's a GOOD THING! Love it 5/5
I don't see why people complain, this is how the games were back in the day. 3 lives is totally right, and makes the game challenging enough. After 15 minutes of playing track 1 and 2 are sooo easy. Finished the game in under 30 minutes... the attention span nowadays... phew.
This game is definitely one of the best Flash games and I've played a few. It even made me do some challenges for myself, at first I tried to finish level 15 with brilliant without casting any spells, but I couldn't make that work, the ninjas always manage to touch the gems. Then I tried to finish level 15 with only using High ground and no spells and getting Excellent, but I lost one gem. :( But extremely fun anyway.
