A free and open-source "clone" of Super Hexagon. However, do not underestimate the quality of Open Hexagon based on its "clone" label. The game features genuinely great music for such a project (including FantomenK and Bossfight), as well as plenty of levels with some creative gimmicks, fancy graphical effects, a level editor (with a niche but fairly active community surrounding it), and other fun things.
Another game that I used to play as a kid (because it's /free!/) but I wasn't good at it. In 2021 the game got revived and released on Steam (although you can still compile it from source code for free if you like, and I even packaged it for the Arch User Repository). Anyway, I tried playing it again as an adult, but I am still not good at it. Probably the one flaw in this game is that the difficulty curve is nearly endless: Super Hexagon was challenging, but bite-sized in comparison. On the other hand, I have 15+ hours of Open Hexagon on Steam (and some hours playing my compiled version offline), and I am nowhere near being able to complete all the levels, even though by now I can complete Super Hexagon in less than 15 minutes. Anyway, this is a very well-made game, but incredibly difficult, thus I never beat it.
