ClickRisk - nice game! Could do with:
- instructions somewhere on screen
- escape to exit
- a non-fullscreen version (I hate fullscreen apps

)
- different speed blobs (maybe in different shades or shapes?)
- maybe a title and a "click to start" sign before the game starts?
FetRisk - Not really my sort of game, still nice impl.
- Controls seemed a little unresponsive
- When a block falls due to other pieces disappearing make it instant otherwise it can get pretty muddled
- give the blocks some texture.. just plain blocks look a little tired

Fifteen - Now this take me back. I love it!
- Could we have some jazzy colours
- Make block move on mousePressed not mouseClicked. Clicked means the mouse up and down have to be at the same pixel, makes the controls slower.
- How about a time limit?
- How about a choice of boards (sizes?)
All in all, very cool showing.
