I distinctly remember the carpet having a red and white checkerboard pattern.
The environment is just the sky, with the frequent rain: the objective is to prevent the carpet from being flooded by raising specific parts of it, forming puddles.
I was playing this game approximately 2 decades ago, on Windows XP. However, I'm pretty sure it originally came out for Windows 98.

I should've probably mentioned I remembered the platform's skin changing as the game progresses, but I wasn't completely sure about it.
