Very well designed! I finished the game on my own in around 4.5 hours. Simple mechanics but used creatively. The last four levels really challenged me. But the feeling of solving something that felt almost impossible is really really great. Thanks a lot for this wonderful experience.

For those that want happen to read this review while struggling to solve the latter levels but don't want to watch a full solution, here are some hints:

[Spoiler ALERT!]

Great puzzle games often utilize all the game mechanics, especially towards the end. Hence a good solution should have everything "fall" into their correct places. Also the solution is usually a "one way ticket" to glory. Both in the sense that you can't unsee the solution, as well as gameplay.

While the Crab is symmetric, the solution might not be.

Dino and Crab can be scary to even start to tackle, but trial and error can lead to great insights. Solving a simplified part of the big picture can also be making progress in unexpected ways.
