Robots: create AI

Looks good. A bit obtuse UI, lacking in instructions and could use a button to speed up test runs. But as of now I do not recommend this game. After playing for about an hour I discover that the game is not saving. Even for such a cheap game that is an unforgivable flaw. Will not play until this is patched.
Edit: Seems that there is no patch or even comment from the developer. Stear clear of this game!
Edit 2: Saving seems to be working now. Updated recomandation.

Fun little game. But for the moment i can not find a way to save.

Is it worth buyin for a buck? Yeah, it's worth a buck, but don't expect more. If you like puzzle games and you're okay with the video and screen shots above, then you'll probably get a buck's worth of fun out of this, maybe a bit more.
It's not the easiest thing to grok at the beginning, but undestanding comes soon enough. You can click the current instruction (except not at first in the initial level), or above or below it to add new instructions. You can right click to get rid of an instructions. Re-nesting is a series of adding new nests and removing parts to get the bigger nest to re-align and work.
Biggest problem with this game is that you have to grind through batches of levels that essentially rehash previous levels, so there are chunks of annoyance. Also, the game does not save the work at the current level, but does save previously completed levels. So if you're working on figuring out one puzzle and have to leave it, you either have to finish it or restart, but it's a simple enough game that that isn't really an issue. Also, the aligning of instructions isn't very good, so complex rule sets become cumbersome, which is very unfortunate.
Eventually you get new bots that help speed up the time it takes the bots to run through the solution, though lackluster if you're hoping to get bots that change the game (though I'm not sure what the last bot does yet).
So, yeah, if you're willing to spend a buck on something that will give you a bucks worth of fun, and you like terse puzzle games, this is a decent buy. Otherwise, move on.

If you like the game of Zachtronics, then this is right up your alley - programming as gameplay. It's delightfully obtuse but rewarding.

Definately recommend this game, the levels may take some time, but it's all worth it just to see that you finish each level and go on to the next, the game is definately a great game if you like to test out and create A.I., the developer did a great job developing this game!

너무 재밌어요
더 복잡해지면 비용을 더 낼 의사가 있습니다
재밌는데 쉬워서 아쉽다

I like it, a good small scale programming puzzler. A little obtuse in the UI at the start, but it's simple enough that you pick it up quick. Someone mentioned their saves weren't tracked, but mine are fine.
