Block off is an interesting game, and it is very impressive. I found it to be a bit trivial, because I could rotate every block in any direction. I had so much freedom the game never posed challenge. I think it is a really strong foundation for a great game.
I found binary madness confusing. I would make the 4x4 board the default and add an image of a completed puzzle to the the instructions.
Marble maze is really well made. It is a technically impressive game. In writing we have a saying. "If you want to make a side character interesting give him a limp or an eyepatch." Marble maze is a good game. It does not have e gimmick. The little axis thing in the corner of the screen was really helpful. It made the game a lot more friendly.
I would appreciate it if you could give feedback on Allura of The Bully. :)
