First of all, this is awesome! Great concept, super useful design, and nicely polished too.

Second, just a question - what tools or libraries did you use to make this? I’m just starting to get into C++ game development and I can’t help but be impressed that the download is only one file, and 200kb at that. What would I use to make something so streamlined like this?

Doesn’t seem like SDL since you’d need to include the DLL in the download... anyways, obviously not a super important question, but I really am impressed and want to learn how this works.
