This was interesting! I dig the idea of a platformer with platforms that shift and align in this way.
When playing for a long time, the music track didn't loop, and attack as down is very uncomfortable for my hands, so I wasn't able to spend a lot of time with the game in the end.
I'm uncertain of whether the game is intended to be endless or whether it has an ending. Comments on the game page seem to suggest it does - in which case, good work!
Shipping your binary as a loose file means that it doesn't have executable permissions when downloaded - something that is needed in order for a file to be run on Linux. A zip archive can hold these permissions. If you are on Windows, you may want to consider setting up a Linux environment or using a tool like this one so that you can set the executable permissions that will allow your Linux users to run your game without having to fiddle with permissions themselves.
