Finally I have released my puzzle game "Unblocked". It is very close to NES game "Flipull" but my game mechanics differs a bit.
Here is a small screenshot(bigger one you can look at game documentation page )
Sorry, I am no artist, so the game does not look very nice
I've tested the game on Windows7 64-bit(project release page includes compiled binary), and on Ubuntu 18(I had to install a few developer libraries - README.md contains the list).
