Fun. Make a nicer background, spiff up the art a little, and add some visual and temporal cues for events - there's no pause or anything when you die or beat a level, which means the player is still holding down the key as the level starts/restarts.
Truly great idea, truly horrid execution. There's a fun game in here, somewhere underneath the crummy control, infantile art, and overcomplex physics. (Of all the things to add in a tower game, elasticity???!?)
This is neo-retro and akin to classics if "retro" is taken to mean early 90's shareware and classics in the Big Blue Disk sense. 2/5, and I'm still waiting for the twist. Or the fun.
