You should give feedback :)

Tips:

Placement is very important! Towers should make good use of their range, and seeing the track at multiple points greatly increases their value! Also consider things like attack style.

Certain towers can synergize with eachother, not just by increasing their damage, but by giving each other more time to work!

It is intended for the player to make use of Gold Mines. However, it is probably possible without them.

Oh, you're looking for the volume slider? I spent all my time making the game good, use system volume or mute the tab if you don't like my mediocre music.
