The current Game Maker that can be purchased is the Studio 2, this game was made with the Game Maker 8.1 lite (you noticed it by the watermark). A part that your comment was short to consider as a valid recommendation.
Your games very simple, who will be play?
Well, whoever wants to play.
Yours are also simple, but they had their charm, at least I liked the Hoopi World.
Do you draw sprites yourself?
Yes, often.
