Fix the position of the multiplication sign
In the levels on ios, where the equations are on a straight line, the multiplication sign is too low. It resembles a punctuation sign.
Also you could consider the ability to drag a 3 onto a 5, resulting in the propper calculation.
Otherwise - really great app!
WRT the multiplication levels on later islands, we are aware of the issue and plan to fix it in a later release
WRT to the ability to do arithmetic, it is a feature that is available in the game, except it is not enabled in most of the levels in the current version of the game. A bit of it is available in DragonBox+. The main focus in DB was in basic algebra. We are going to add new levels with more focus in arithmetic in a later release as well.
