Very nice game you made! How long did it take you? The graphics are really nice and I am surprised to see GB Studio pushed outside of its confort zone :)
These highscores are tough to beat thought! :D How do you get up to 666 in the platformer? ^^
My only "complain" would be how the rocks in the space game tend to damage you even when they are far away, so it often get quite messy if you happen to be at the wrong place at the wrong time. Otherwise congrats, cause there are a lot of well-executed ideas and I'd love to see them more polished! :)
