I’ve never given 5 stars to a game with ads

It’s refreshing to find a fresh puzzler with a new, unique mechanic. It’s a great game, very inventive so far. It’s not the best puzzle game I’ve played (Id rate Yankai’s Peak as better) but really really good. I’ve pretty much played all of them that I can find.

It’s free but I wish I could pay $2-3 to turn off the ads. :( They aren’t super obtrusive but they are there. I typically delete a game immediately if it shows me ads but this game is engaging enough I’m still playing.

They also waited an appropriate amount of time to ask me to review it (I’ve played maybe 40 levels) so kudos to them.

Hi Fryslie,
Glad to hear you're enjoying OCO so far.
If you go to the shop you can in fact remove ads for $2.49!
Thanks for the feedback.

Good but...

The game has good potential and I have uploaded 57 levels so far, but sometimes I can’t and the blue upload button turns gray and when I tap it, it says slow mode activated. I have no clue what that is or how to get rid of it. I have to RESTART the WHOLE game (and sometimes it doesn’t even work) just to remove the slow mode thingy. Because of this, my level gets deleted and I had to restart it from memory. So why not put it in the save thingy? You might ask, well it just saves the name, not the level, so the save thingy is USELESS!!!!! And now, I don’t know if there’s a limit or something, but I can’t upload a certain level. (I tried 3 times. Still didn’t work.) I put it in the save thingy just in case, and made a new level. This time, it said the same slow mode thing as before, so I just gave up. After this thing, I’m not playing OCO until you fix those things and take away the terrible slow mode thing that I don’t want to explain again. (Please?)

Hi Dreik78.
The slowmode function is designed to prevent people from spamming the 'new levels' page. After you've uploaded 3 levels you will have to wait 90 mins before you can upload again.
We've not head of any one else having problems with saving levels, can you please contact us here and we will help you resolve the issue.
Thanks for the feedback!

Best game ever!

This game is so fun and entertaining. It is difficult at times, but not so difficult that you can’t play. It also includes a feature where you can create your own level and play other peoples levels. My only problem is that there are adds, but not to many. I like how you can get 200 bits just by watching one add. Thank you for creating this awesome game!
