Originally made in less than 72 hours for Ludum Dare 35. Updated with music, sounds, and special FX.

It's a nice Sokoban like game, and I'm always impressed by anything made in as short a time frame as a ludum dare entry, but I was a little disappointed to read the comment that mentioned the game is an adaptation of another game. I looked up a video and this game is essentially a remake of Pegs with new aesthetics and levels. I think if you're going to remake a game this closely, the original should at least be mentioned on the store page or in-game credits. (according to the video, it's from the PuzzPack by Detached Solutions, and its main developer was Fred Coughlin). Also, the original said "Nice pegging!" when you completed a level, which is funny in a juvenile way and i wish was in this version.  There's a suggestion for iego DX.

Glad you enjoyed the game!

You are correct that Detached Solutions should at the very least be mentioned on the store page and credits. It has been added!

We did have it mentioned on the store page some time ago, but I'm not recalling why it was removed. The game cannot be updated to include it in the credits, but acknowledgement will be given in the credits for IGEO DX.

Thanks again!

Will you be updating this to support a 64-bit architecture so it's able to run on macOS Catalina and higher? Thank you!

Thanks for supporting the bundle and your interest in IGEO.

Sadly, IGEO was developed on a version of Unity that we can no longer compile the game from. We tried to upgrade the game to a newer version of Unity last year to address this and some other issues.

Due to the games reliance on deprecated libraries and changes to the Unity engine we decided the game needed to be rebuilt from the ground up. 

A more formal announcement and an open alpha test will be coming in a few weeks for IGEO DX, which will support MacOS 64-bit.


Hi! Found your game randomly scrolling through the 704 games in the racial justice bundle; thanks for contributing! I basically like the concept, but I'm really held back from enjoying it by the lack of undo support.

In the puzzlescript era undo support feels kinda required for games like this, and honestly the friction of having to restart (which is also quite slow) is causing me to not want to finish the game.

I don't mean to act entitled to your time, but if it's not too effortful to add undo (and maybe a faster restart), i would certainly play the game to completion, and I suspect others would be less likely to bounce off it as well.

Thanks for checking out IGEO and supporting the bundle!

Unfortunately, IGEO is not really in a state where content can be added any longer. 

However, a new and improved version, IGEO DX, will be coming into open alpha later this month and undoing moves is an included feature amongst loads of new mechanics and levels.

The open alpha will be free and the full release on Itch will be free for anyone who has purchased IGEO.


Great to hear!


I passed the Windows version of the game. I really enjoyed! But I would like more levels : ) However, the existing levels are amazing. In the 16th level I found a bug, attached a screenshot, on it the player’s block is in the wall, apparently there should not be a wall (by the way, you can pass through this wall in one direction, but not in the other). Perhaps without passing through this place it is impossible to pass the level. After passing through the 20th level, by the way, for some reason, it is closed in the level selection menu.

Have you come up with this concept? He is genial in its simplicity. I have never seen this type of game, if you invented it - you are great fellows!!

I have ideas for new elements and features, if you are interested, look in this online google document.

Thank you very much for your game, it is wonderful.

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!
