You can try with this

• Go to editor
• Remove both hints from the top row
• Playtest

It will show no hints on the bottom row, and shift everything up

A list with sizes of aquariums that MUST be present

Right now all buttons always reload as visible

I think we can use the hints themselves, as they are ignored

When for example dragging to add water in multiple places, a single ctrl+z should suffice to undo everything. Minor.

When it's a very long horizontal aquarium, since it only looks for water levels on the immediate right or left side

Right now it has aliasing

There should be an exact number per level

That means doing backtracking.

Right now it only saves when you exit the level. Every 30s or 1 minute should be fine.
Also save when you quit the game. I think it does, but only settings.

Only allow valid moves

All waters/boats must be together if {} and not all together if --

It opens the same level but with fixed hints where you can test the solution.

Possibilities:

• Open a file using system dialog for opening file, we always edit that file
• Store the levels with the saved data. We need to handle listing those and creating/deleting them. A little more work but nicer, will integrate better with steam, both for workshop and save cloud

Generate random aquariums, fill them up randomly, get the hints, and erase the waters.

Or make everything work with blocks without walls

When the length is greater than one

solver never puts them

Now it does it correctly for a column, but not when rising water on (i, j) requires cell (i + 1, j + 1) to have full water

Add/remove 1 row/column at a time

Alpha should change when pressed like the others

Start just with a 1x1 fish that needs to be in the water

Needs a DP to do subset sum and see if each component is "useless" or "necessary"

That's because it's always satisfied, as we update the hints.

Solutions:

• Only on this screen show the total, instead of remaining? Will it be confusing?

On the rightmost balls, you can't click on their right side.
