Thanks for your kind words! I'm glad you enjoyed IGEO.
I am not the original inventor of this game's concept. It is a mechanic derived from an old game known as PEGS on Texas Instrument calculators. I've adapted it into an isometric form, which adds a unique bit of challenge to it.
I am currently exploring taking this concept further by introducing new shapes and mechanics and adding more atmosphere and variety to the game's art and graphics. It will be re-imagined in a lot of ways. Also, thanks for the suggestions. If I find a way to fit any of them in I will certainly let you know!
I'll take a look at those bugs and see if I can whip up a patch. Thanks again for playing!
