Really good game. I liked it. Good work!

I loved it! Couldn't stop. Played to the end.  Excellently done.

Some of those sand grains do like to escape though.

Such a badass unique incremental. Never though I’d want blue sand! The game feel is so good that it makes the upgrade experience addictive. Good use of sound, music, visuals, numbers and UX. That nudge has a good feel.

The concept is interesting! Good game.

For a game jam entry starts a little bit slower than I would like to - it took me a while to actually get it going at a decent speed haha. But that's not really valid critique - your game is great, very cute art, and very nice idea. I am still waiting for the final unlocks but I already can say it is a solid entry. Great job! 

Edit: I just had to edit and increase the graphics rating because the hourglass becomes BEAUTIFUL  once there is a lot of sand in it!

That's a very unique take on the theme and on idle games generally, I really, really liked it.
Awesome work!!!

Really liking this concept, very well done!

It's an interesting concept, it's kinda slow at start early on. After playing for some time the rotation stopped working.

It's a good idea, and I like the small investment tree, but it's a shame it's a bit slow to start; perhaps a bit more dynamic would have been better.
