Agh, I've also seen the Play Store version is gone too probably due to Google delisting anything older than two years. Could you upload the latest build you have for educational purposes? I'm currently teching a class of gamedev and we're studying your games and I can't for the life of me get a hold of this one :)

Any chance of re-exporting it so it works as a 64bit app on mac? The OS stopped running 32bit 4 or 5 years ago or so.

DOES work on Steam Deck, ONLY if you edit the launch options to "Force the use of a specific Compatability tool" and set it to "Proton: Experimental."

You should totally make Circle Affinity a paid add-on or sell it as a separate game. I've been playing it on my phone but would happily pay to have it here, too. I just can't seem to get enough circles!


This doesn't work on mac due to it being 32bit. Would you be able to update it so I can play? :)

Hands down one of the best and certainly one of the most original and most stylish jump & runs I played in a long time. It easily combines brain melting visuals with challenging and varied level ideas that are equally challenging for your fingers and eyes and continuously amaze with new visuals and twists (ha) on the formula. A bit surprised there are no times/speed running options here as figuring out the mechanics is already amazing, but nailing the movement of a level into a perpetual motion is downright mesmerizing. It combines the best of twitch action games with platforming challenges wrapped up in an interactive piece of digital art. Downright amazing and jawdropping. 5/5

More Racial Justice Bundle impressions

It seems like this version of the game is missing the Circle Affinity mode that was added to the Steam one.  Are there any plans to add it? I would like to play it.


We are looking forward to discussing Circa Infinity LIVE on Thursday, December 10th at 7 pm EST  on Indie Game Club (it’s like a book club for indie games)!

Apologies, but my Mac thinks this game is broken and should go to the Trash. Not sure what's up… I know I didn't get a Steam key; maybe that's the issue?

Does not work for me either, on MacOS 10.14 (Mojave).

I determined that the start script (Mac_Runner) is the broken file. But it's broken in a way I cannot attempt to repair. MacOS can't even open it in a text editor!

my brain is fucked lmao

Very unique and interesting. Great idea!
I'm still at level 1, but I'm looking forward to seeing how much harder the controls and decisions will be.

Pretty cool man, It's a relly decent game!

An interesting gameplay - totally unusual and fun. A really good surprise which I bought in the racial Justice bundle with thousand other games. This one is amazing. Thank you ++
