Harder than Dark Souls. Still realy fun. 
I imagine other people have discovered this, but if you mash th drop buton, the pipe that drops the boxes grows to the point of covering the entire screen.

Cute little game, really like the style! And made in 48 hours too, wow!

Good game! The concept is really fun, and has an addictive gameplay. I could really play this game for hours

I keep overshooting the size of it for so little... Great game, doubles as something to help with measurement by eye skills.
Also,  found out that if you keep clicking the fit after fitting the square enough, it will shrink out of screen. Some more and it eventually fills the screen. Guess that even the glitch makes a perfect fit.
GG

Really addictive, I could honestly be lost in this for hours. I did manage to get one perfect fit :) I love the vibe and the music its very soothing and the game focuses on one core mechanic rather than trying to stuff a bunch of things in, which is refreshing :) Good job!

Haha! Cool concept!
I think that maybe would be cool to have one or two more tries to fit it perfectly!

Oh I've had so much fun with this one! And it's made in 48 hours, music included?! Whoa. Only note I have is I'd have loved to see something like a percentage too for a score, as a form of more detailed feedback

So friggin close... (to perfection), this triggers my perfectionism mood. So just 4/5 for enjoyment!

I don't want to admit how long I played this for! Way too addictive!

Damn, that music made me 5 star it for enjoyment, may we all one day fit perfectly

"build to scale" : wow, you don't mess around with the theme, it's straight to the point ;-)
As everybody says : simple yet so fun ! It misses some kind of mid-term / long-term gameplay, please keep going !

Really cozy and interesting idea! Lack of completion/goal made is slightly less fun I suppose, but was still fun to play! The simplistic art and music fit the gameplay perfectly :)

Soo unique, yet not complicated! Satisfaction from perfect fit is here, yes! Artstyle is good, too!

Fun and simple idea. good job.

Simple yet really cool game! Hard to stop playing until getting a perfect fit xD

Simple yet addicting, and the vibe is on point!

Beautifully clean and amazingly satisfying. Plain simple fun. Great Job.

Damn!! So clean and immersive. WHat a satisfying and quick playloop. Well done

This game is so simple, it has no right to be that addictive!
But it is and it's awesome!
Great idea and very well done!
I don't have a lot to say but I always give constructive comments so:
The sizable square could come back to the smaller after each fit
The grid in the background could help a little more

Besides that, great job!
