The concept is really nice, and the sand doggo is adorable. I really like the hourglass mechanic because it makes for some interesting movement, but I found the levels to be somewhat difficult and reliant on memorization. The fact that the dog keeps some of its y-velocity after flipping makes it so flipping right before hitting a spike still kills you. I can understand why that would be done, because otherwise, the player can basically fly by spamming the flip button while mid-air, but because there are spikes outside of the player's view placed right underneath them, the player needs to memorize where they are and shift to the side. There's this one spot where this is subverted, and instead of landing at the side, the player needs to hold still. At first I thought this was clever, but then after a lot of restarts, it became a point of memorization. In my opinion, if the game is this difficult, there should at least be a checkpoint in the middle. What I did like though was the art- the cutscenes are great, the background is clever and helps with reorientation, and the sandpeople are nicely designed and named. If the game was a little more fair to the player, I'd enjoy it a lot more.
