Tips and tricks
- Read the whole board before your first move. In most puzzle games the first move is the most important one, and it deserves ten seconds of looking.
- Do not memorise solutions, memorise principles. The level after this one will use the same idea in a new arrangement.
- If you are stuck for more than a couple of minutes, step away and come back. Puzzle solutions often arrive when you stop forcing them.
- Use undo or restart freely. Experimenting is how you learn the mechanics; there is no penalty for trying an idea.
- Because this is a Hypercasual game, find the rhythm of the single mechanic — that is the entire skill.
- Because this is a Pixel game, pixel games often have very precise hitboxes — trust the sprite edges.
