Cubology

Sorry, I forgot to add the following to my comment above:

I've tested all of the games offered by PieEyed games. Microsoft Defender flags most of them, but all 'are safe' to install.

Nearly all of Pie Eyed Games are now free via Itch.io, i.e Arklight, Circulate, Cubology, Darkside, Kitten Sanctuary, Mirror Mixup, Pyracubes and scavengers. These cover some of the popular arcade games from the Noughties i.e. Match Three Breakouts, Shmup's, and other puzzle games. All very playable and well worth the effort. Follow the link provided by the Admins and it will take you to the appropriate page. You'll also see all of the other games available from the developer. The only one not found on here by PieEyed Games is citadel 1986, which is also free over on itch.io. However, Itch.io also gives you the opportunity to donate money to the developer instead of downloading it free. I've tested all of the games offered by PieEyed games. I also bought all but Citadel back in the Noughties and also Beta tested some of the developers games for him. My versions include activation codes, but you don't need them for the ones via Itch.io
