Collaps  
it's a nice clone, but it - sorry to say - needs some developing. when my blocks reach the top of the screen the game crashes down to the desktop; no highscore - nothing... maybe you can also let the background and the blocks use one gfx-theme (rocky background - rocks as blocks).

Jumping Jack 2 : Worryingly Familiar  
it's a really nice remake, you've done a good job, Neil. the windows binaries i used work fine even on slow machines (p300), but maybe you can do some gfx-polishing and remove some graphical glitches. to say it again: it's a good game :)
