However, even if I didn't know the developer, I would still call this a great game. It's well designed, and can get you hooked easily, so be careful or the hours may fly by while you try to beat your high score. Well done for your inaugural game, Color Blind Studios! All the best wishes! ### 5/5 — High Score *2016-12-21, version 1.1.1* New high Score is 186, what's yours? ### 1/5 — Need update!!! *2016-11-14* New scores are not coming up on the ledger board!!! ### 5/5 — Great Game *2016-11-06, version 1.1.1* Challenging and has you coming back to beat your highest score. ### 5/5 — Amazing *2016-11-04, version 1.1.1* Cool game, loved the story 11/10. LivvythebubblexX ### 1/5 — New version *2016-09-27* I don't like the new version. When you have to rotate to change the color. I like the old version when you have to tap to change the color. ### 2/5 — Too many ads *2016-09-21, version 1.1.1* Fun and addicting game. Too many ads though. If you're not very good at the game, you'll be forced to watch a high number of ads, as they seem to only appear after a few games played. It should be changed to a timer so that you only have to watch an ad every x minutes, instead of every x number of games played. ### 5/5 — It's worth playing *2016-09-14, version 1.0.3* You can challenge your friends and stuff, plus, it's really mind battling ### 4/5 — Great fun! *2016-09-02* I loved it! But the ads were excruciatingly long and played so often that it really ruined it for me. Anything you can do about that? ## Frequently asked questions about Nukleus ### What is Nukleus?
