I wasn't expecting much out of a Stencyl. however, this game was okay, but it could have been so much better. There was nothing to collect and there was no point in exploring other than to find the door or if you were really curious about the game. You could have had the character take pictures of the skeletons or given him a weapon to kill the monsters with (why didn't the monsters harm the main character). You also could have had text pop up in between loading screens after you go through the doors to reflect the main character's reactions to the planet. It may have also been better if the song was a bit longer before it looped. I have to give you credit, though. I didn't come across any bugs which is rare for most of the Stencyl games I play.
Try playing Gyossait on newgrounds if you haven't already to see the potential that Stencyl has to offer users. Good luck with your other games.
