Thanks for the feedback! I get that some modifiers can be frustrating, especially early on, and their combinations later in the game can also be annoying.
This will be improved in the next release. Modifiers will be introduced gradually and will have different difficulty levels, so you won't encounter the random numbers early on. An explanation will also be shown when starting a level.
The random numbers modifier is easy to deal with once you figure out which number corresponds to which, since they aren't completely random for each cell but are simply remapped.
Hope you'll give the game another chance in the future :)
