What’s New

Version 2.0

Kotoro is back!

We have remade the entire game on a completely new game engine and we hope you enjoy it.

What happened?
The original game engine we used to develop Kotoro was no longer being supported so we were unable to update the game to meet the 64-bit requirement for the newer iOS versions. As a result, we have remade Kotoro from scratch on a new game engine. If you've bought the game before, you can download the game again for free with the same Apple ID you initially used to buy Kotoro.

What's next?
We are thinking about adding a new chapter to the game further down the road. Meanwhile, if you'd like to support us please consider purchasing our other games on the App Store.

A game for the wise

This isn't a typical guess and check puzzle game that you find on the App stores among us; this is an honest to goodness logic puzzle that requires you think 3, 4, 8 steps ahead if you actually want complete the game in a timely manner. Just checked the game center and it tells me I completed the game with 392 combinations. I'm betting the minimum number of combinations is around 320, and probably 2.5 hours to do so. (There are currently 72 stages with average 5 objects to it (350 moves), so that may be underestimating it)).

Hope every one enjoys and I'd love to hear more from others about how many color changes it took them to complete the game (It's in game center).

It's just ok.

The object of the game is to change your clear orb to a specific color by absorbing other orbs around you. Some colors can be mixed together (primary), some can only be absorbed by matching the color. It is challenging as you go along, but the game had good instructions.

I am not crazy about this game so far. Maybe it gets better at higher levels, but it's just not a fun game for me. The graphics are good but basic; other reviewers say it's "minimalist". However you describe it, it's not what I expected. The game play is not interesting to me. I don't remember what it costs, but if it's more than a dollar, it's not worth it.

That's just my opinion. I read the other reviews. Most are really positive, so it's obviously not a bad game. Just not interesting to everyone. (I never understood the appeal of Zenbound either, and it is one of most loved and highly-rated iOS games ever.)

Favorite Puzzler right now

I hate the stupid fast-paced games that are more about luck than thought. I have a special interest in color, being an artist. This game is great not only for honing your basic subtractive RYB color scale skills, but also challenging your brain to solve problems. I'm on the "replicate" chapter and think that this game was well-thought out and implemented.

It would be interesting if they also added some levels using additive colors, as the RGB color-mixing would be a new challenge for me.
