Hey Tomp23CZ, thanks so much for your submission! This felt like a real game the GDD might have made - very Atari-like. The difficulty being determined by actually changing the window size was also a fun little quirk.
That said, there was a lot you could still do to populate the game a little bit. I'm not certain if there were differences between Momoi and Midori, but it didn't seem like there were. Speed, length, intensity, etc. could have varied the game a little bit. In that vein, I strongly recommend using backgrounds, SFX, and a BGM for your next games just to add some easy flavour.
I look forward to seeing your next titles! Stay tuned for the rankings on Sunday.
