So a few things. The concept of the game is great, picking up sand in order to progress is something I can greatly enjoy, but what can help is a little bit more conveyance. Before I knew the Hourglass was the yellow triangle floating above with a timer, I had just speed-ran through the game until I reached the top, and even then I was late by ONE SECOND. Safe to say I got frustrated a bit, until reading through this submission page where I discover the yellow triangle is actually an hour-glass. "No way!" I thought to myself, but after doing a test it was indeed an hour glass which made the game significantly easier. Another example of this is picking up sand and placing it, I didn't know if I was holding a sand block or not and the only way to know is by spending a couple of seconds to press the spacebar in a safe space. So yeah, I think your game has a conveyance problem, but I do like the concept of digging the sand. Would love to see something come out of this.

TL:DR;

- Didn't know the triangle was an hour glass

- You never know if the player is carrying a sand block until it's too late

- Gameplay and Concept is great and would like to see it fleshed out

I got very close to winning before realizing that you can (must) feed the hourglass. I feel like you can probably do something in-game to indicate that possibility, even if it’s as subtle as making it clearly impossible to win without doing so.
