I love this game a lot - seriously, last night I spent THREE HOURS PLAYING IT and didn't even notice until it was almost midnight.
- Have clues stay visible on the side of the screen rather than disappearing after a few seconds.
- Have a way to mark potential ladder candidates.
- MORE INFO TILES. I keep having to resort to strategic Cross Checking to get a hint as to where the ladder is. Luckily I save up a lot of them.
- Some way to easier to judge probable master block locations. Again, some kind of marking system would help a lot there.
