Nice core game, but if the developers can’t even figure out how to make separate controls for music and sound effects, they deserve to have their games rated 1/5.
Oh, lord, that Frozen Peak level on Hard was.. really hard. I tried about ten times using earth and air and finally used water and air. The fully upgraded water towers were my only defense against tree wizards, though, and I had to let one slip past. The only way that I beat the level was to never let the next wave come early, so I could have time to regenerate my spells.
