It's kind of meant to be tough :) The shooting guys can't target you if you're standing only one tile away, so that's usually the strategy - to keep them close. Also they won't shoot at you first time they see you, there should be at least a turn of delay (however it is sometimes possible that they will see you sooner than you notice them)
The wands are also melee (but you can stun them so they won't run away :)
Yeah I have some still unresolved problems with various screen resolutions and font sizes. But I've had some technical issues (mostly on mobile) that needed to be solved first. Thanks!
