The first post-jam update is now available!

I've made quite a few improvements since the last devlog, but I had to draw a line under it somewhere and get it out there.  The big changes include...

• Implemented the large drone enemy type, with behaviours to attack plants as well as the player. This enemy fires instead of just coming for you and dealing contact damage.
• Added difficulty levels, and tweaked a lot of stuff that contributes to difficulty like enemy wave patterns and plant water requirements.
• Added a crude collision avoidance behaviour for enemies, to stop them getting stuck on walls and blocking each other.
• Animated the existing background shopfront art, and added a second one.
• Some other art tweaks, like grime on the walls.
• Added a tutorial!
