+-Rooms 

A minimalist logic puzzle game based on the principles of math

Each level presents a small room filled with numbers and operators.
Your goal: Remove every digit and every symbol by creating valid equations through movement and alignment.

Slide numbers into place to form expressions like 3+4 or 5-5.
When two values and an operator align correctly, the equation resolves — merging numbers, canceling out values, and slowly simplifying the room.

Controls:

W/A/S/D - Move

R - Reload

Esc - Escape / Get your Mouse back

MathRules:

When two digits are separated by a +,
they get added together

If the result is 10 or higher, it creates two digits,
on the position of the first digit and the +

When two digits are separated by a -,
they will be subtracted

If the result is lower than 0, the negative number will be shown
on the position of the first digit and the -

If the result is 0, the special result will apply
and both digit and the - will disappear

These rules don’t only work from left and right,
they also work for up to down

Special Cases:

If one + or - apply in both directions at the same time,
both directions will "disappear" and only one result will be shown (higher for +, lower for -), except if they have the same result

When + and - want to use the same first digit and the + result is ≥ 10 and the - result is < 0, then both equations get applied but the minus takes the place of the first digit and not the 1
