Version 0.43 is out, and includes a range of fixes and features:

• Enemy rendering / performance fix - one draw call for all, instead of one draw call each

• Enemy selection / performance fix - speed up for when towers are selecting an enemy to shoot at

• Upgrade screen UI update

• Main menu UI update, including an animation on the RHS

• Enemies get a speed boost if more than 5 waves are active

• Enemies will wait longer before rerouting

• Reduce the number of times a wall has be broken before the tile it's on cracks

• Bugfix: Game froze if clicking the settings menu while editing a tower

• Bugfix: Clicking a gem in the hotbar for a second time should deselects it

I've also updated the screenshots and trailer.
