I'm upset that this game has been out for at least 6 months and I can't find any references to it on the internet.
Glass Keeper Glabis is a freeware puzzle game about a little robot who collects purple orbs to complete each stage. You have only two abilities: a punch to move or break blocks, and the ability to extrude a block of glass in front of you. The structure is reminiscent of Fire 'n Ice for the NES, but the mechanics are different and the result is a completely different set of puzzles.
The game difficulty ramps up quickly by smoothly, introducing new types of obstacles with levels that naturally show you how they work before building hard puzzles around them, so there's no need for an instruction manual. The puzzles get hard quickly, though, and you'll have a lot of stages that look impossible initially until you logically work out how to bypass some little kink in the layout. It's very satisfying to play.
Do me a favor, and spread this around. It's a really good puzzle game.
