it seems everything has the same crit rate so goblins and things that attack quick will crit more but do less crit dmg you may want to change the crit rate so it's fair
could use a rocket that gets the dmg multiplyer up quick but does less dmg like 10 start dmg but the multiplyer has 50% less charge need and a max charge of 6
if you lose and you have diablo summon him quickly and the game will continue you can keep summoning him and if you have the necromance spell you can get some other units back
when you land on a spike block (or ice or sand) id you sand on the very edge the blocks effect doesnt work like 0 damage from spikes or block doesnt disapear fix it please.
