Heart Attack

A prototype for a tower defense game / sound toy.

v2 allows only one unit per tile, which I think opens up a few more interesting spatial and musical interactions.

Controls:

• Right-click drag to pan 
• Scroll to zoom
• Left-click to buy, place, and pick up units (you can always pick up and re-place existing units)
• Esc to open menu

For testing/experimentation:

• Press Space to toggle the heart shockwave shape
• Press I on the title screen to start with increased money and health

Note: This is not even remotely  balanced as a tower defense game. It's generally very easy once you know what each unit does (just don't buy two blue units at the start).
