Thank you for this! ❤️

Will there be a update to take advantage of the new features?


thanks for the question! I want to, but I just have to find the time - I'll post in the devlog when I have an update


Is there any chance there'll be an ARM64 port of bitsybox in the next update? Because bitsybox won't work on my Raspberry Pi 400 with Raspberry Pi OS 64-bit.

If I sound standoffish right now, I do apologize in advance for that.


Great tool!!!

Tiny bug report: Whenever there’s a fade transition the colors of the game become darker than before (or brighter, depending on whether it was a black or white fade), as if the transition never fully ends. I noticed this bug on macOs, didn’t test it on windows or Linux.

Thank you!! And thanks for the bug report - this bug is fixed in newer versions of the engine, but this is a good reminder that I need to update bitsybox :)


Did a small demo on how to use Bitsy for my college's Game Design club - everyone really liked it! Excited to see more!

that's awesome! :D




Please use stripe or Payoneer since it doesn’t use PayPal’s API. I then can use my credit card/Debit card.


thanks for letting me know! I've set up stripe, so hopefully that works for you :) let me know how it goes


i just love the idea of putting my favorite bitsy games into a little extractable and then passing that around to people like a mixtape

<3 I love that idea a lot!! if you do it I'd love to hear how it goes :D


wow nice


thanks! :)


awesome! An Android version would be amazing!




thanks for the suggestion y'all! I don't think it's something I'd have time to do soon, but I'll keep it in mind for the future :)

no problem

This is wonderful! Gamepad support! However, when I run it on my Mac I just get a blue screen. What am I missing?

oh no! :( this looks like a bug to me -- let me see if I can fix it!

this issue should be fixed now! :) try re-downloading the mac version and let me know if it works for you <3






AAAAAA it's finally here!! :D Awesome!! Playing around with it right now and it works great!! I love the fullscreen mode!!


yay!! awesome! that's great to hear :D

Also hey! Did you intend for the Windows application to have no icon like this? (pic attached)

(Sending just in case it's a bug and such)


thanks! it's not a bug - I just haven't have time to make / set up an app icon yet :) maybe in a future update!


I'm confused. What is this?


it’s a desktop app that can play bitsy games! :)

oh cool :)
