I have completed a level.
High scores after game is over.
Beginning the game, infinitely re-spawning enemies start running at you immediately
Bonus mission - rescue one of the other Thundercats for a bonus
You can choose in which order you want to play these levels
Fire level - lots of fast projectiles flying at you
Water level - avoid the bubbles
Air level - lots of bats again
Earth level - these guys come up from the ground and are hard to destroy
New enemies will often spawn while you're in mid-air
These boxes contain items, they also kill you if you touch them
An enemy blocks the platform and there is no way for me to get rid of him
Another bonus mission - these enemies carry shields and can only be hit from behind
