The game was quite fun and I definitely enjoyed the style and the idea of building a Khruschevka was interesting.
However, I felt robbed when instead of falling into the right slot the window got stuck.
This is a really beautiful short game. The theme interpretation and execution are definitely very creative. And I didn't mind the shader even in the web version; it does add to the overall aesthetics.
I did find a collision bug with a first wall on the third level, the character keeps getting stuck unless you find a perfect spot before moving the platform (a level restart button would've been handy for that).
