I'm not entirely sure what you mean with the fishing minigame. Clicking LMB shouldn't effect the horizontal movement at all. In this .gif, I'm mashing LMB nonstop while also holding down A/D.
At this time, the Wizard Dance mode doesn't have a minimum score for moving to the next level. As long as you finish one level, you should unlock the next one. If this didn't happen, then it sounds like you found a bug.
The trick with the Tower Defense mode is to place the weapons in spots where they can attack multiple times, like corners, or between paths. There are currently three weapons, one with a normal range and normal damage, one with a much larger range and higher damage but longer cooldown, and one with a very small range and low damage, but a much faster cooldown. You're definitely right that this needs to be communicated better; updating the UI is on my todo list, just haven't gotten around to it yet.
Thank you for playing!
