I like this kind of game but it is a bit frustrating to sometime having to randomly start. Maybe there are too many possible solutions for a given challenge ?
Also, I did not have an end screen when winning, is it included ?
I also have "strange" behaviour when multiple cases are turning whit when pressing a button (or is it a functionnality I did not understood ?)
Some suggestions :
- make easier/medium levels for training (4x4 and 6x6 grids instead of the big 8x8)
- give clues on each line and row when the correct number of houses is present (does not mean they are at the correct place, just that they match the required number) - maybe by reversing the colors of the clue (white texte on dark background)
- Cancel/rollback : maybe give opportunity to create "snapshot" for easy rollback (so not storing each move, just the grid when the player wants, so he can go back to this situation)
