Write custom collisions script to make it easier to detect non-solid collision interactions

• Increment when eat food item
• Decrement when attacked
• Item use behavior: increment heart counter and destroy item

Design according to the mockup:

See #1 for layer and tile properties

Add TunnelWarp behavior to check if colliding with Hero or Player actors. If so, warp their position to HeroSpawner.

• Controls
• Heart counter
• Gold counter
• Hero death counter
• Hero kill counter
• Dragon status

• Increment when pick up gold
• Decrement when drop gold or swap with non-gold item
• Item swap behavior: if both items are gold, destroy target item but do increment gold counter
• Item use behavior: if hero NPC is nearby, alert them to GOLD?!

Items dropped in the tunnel (bottom) continue falling into nothingness since they don't collide with the warp trigger.

Modify the trigger behavior to warp items as well as actors.

Use example code from Superpowers Platformer demo to make tree branches solid in only one direction.

Figure out how to get projectiles to work with fire breath and squirt gun

Apply signal processing to key inputs to make actions smoother, and base it on frame count rather than time.
