This is a pretty creative game that has a lot of different mechanics going for it. I like how there are a bunch of different effects to the hourglass to affect the gameplay.
Suggestions/critques
- I feel that the file size for the game is pretty large for what the game is itself. I would expect this game to be less than 10 MB and it is currently 46 MB on the playdate.
- as someone else mentioned. The game can be cheesed by spinning the crank super fast.
- It would be cool if the player could earn more points the closer to all the sand falling out that they are. This would add an extra level of skill to the game.
- It could be interesting to add more effects such as Draining faster, or the screen going dark or the hour glass clouding up so that you're unsure where the hourglass is (might be too unfair for the player).
Overall great work and an excellent use of the crank.
