It'd be great to be able to turn off the sound effects. Understandably there's only like three but I'm glad my ears lasted long enough to be destroyed by the third.
Great game, except for a bunch of things that are horribly terrible... AI is almost the worst in a game, time challenges are impossible, attacks and abilities often just don't happen, game slows down immensely when there are more than 10 entities on the screen, some enemies glitch and can never die so you have to quit and restart, your character is extremely overpowered compared to your allies, you have to farm to get enough gold to get most upgrades after the first few levels. Great game, I just think it should have been finished first...
Noted... I like the idea of controlling sfx and music separately. As a quick fix, I just lowered the volume levels of the sfx.
