Could be 'Bloxorz'? Really simple graphics but super addictive gameplay, basically just had to flip this rectangular block throughout the stage to fall into the square hole. Not sure if there was any chill music tho 🤔

That description sounds familiar... Was it 'Rush'? No wait, 'Rush' is more recent. You might be thinking of 'Sokoban' or one of its many clones. The original Sokoban was from the 80s but there have been a ton of remakes and similar games over the years, especially around the 90s and early 2000s. These games usually have the chill ambient soundtrack you mentioned and are all about pushing crates to solve puzzles. The original had a warehouse worker character, but many clones just stripped it back to blocks and a puzzle space. I'd check out 'Sokoban' clones from that era.

LOL are you sure you're not just thinking about Windows screensavers? tbh that sounds better than what you're describing

Need more details man. Were the blocks like Tetris or different? Did you have to escape a level or just clear the blocks? Any power-ups or was it purely puzzle?

Hmm, there was this game called 'Kula World' but I think that was Playstation... Did the game you're thinking about have a level editor? That could narrow it down a bit.

Def sounds like you're thinking of 'BlockOut' or maybe 'Intelligent Qube'. IQ was on PlayStation but it had a similar vibe to what you're describing.

omg sounds like Chip's Challenge! used to play it for hours on my old windows comp. those were the days 🕹️ the music was sooo calming
