(n)everraining land could be renamed as I wrote it. After 'immune to spells' it should also either say 'that do not target all creatures' and or 'that you do not control', because my enemy stone rained theirs. I didn't want to check with my own, because I adapted my strategy which is hurt more than helped by using that. Tangientially, stone rain could have an upgrade that decreases its damage to your own creatures. _(c.c)_
I think any last ball of level 25 will be impossible to satisfy, and if so a parallel horizontal slide >2 in and a vertical one at either end, both skinny will make it possible. Also bi-no-colored seems like a bad euphemism.
Snipers can be moved around faster than they can aim. This is a roguelike, which means the point is losing means starting over. I wish one of the levels was called Don't right click, heh.
