I think, Mekorama is fun to use and never gets old as the members are still sharing their levels. And as for Odd Bot Out itself, I think it is good, but bit childish. I completed all of its levels. And I should say the game couldn't live quite long compared to Mekorama and Fancade. Fancade is the most open-source than Mekorama. I mean, you can make a real game from it, whatever you want. But it is complex than Mekorama. So still, for me, Mekorama beats other of Martin's games.
I finish the game there 100 level on the ending you will see the grass and all blocks to build your level
I have Odd Bot Out on my device & go to it occasionally. I like the way the bots stretch; I wish B could do that now & then. It's 2D, so looks childlike, but it's a forerunner of Mekorama, so not as sofisticated. It is satisfying to get the bot out at the end, tho. ;-D
