The overall construction of the landing page is nice and I like it. However, core elements such as the color scheme is, to say it delicately, unusual in a not-so-positive way. While each color alone would work okay, when put together, they look very unappealing to my eyes. I cannot find any relation to the "subject".

Already mentioned it on Twitter, that polish version can't be used because script can't read polish letter like ąęłśżźć etc. Plus dropdown should let me type first country name letter instead of scrolling and searching.
