A prototype for hypercasual mechanic
Player is controlling the "Hive" in the center, it's constantly gaining energy and can grow when fully charged.
Enemies are attacking the Hive and player have to spend the energy to defend itself.
The key feature is the ability to choose attack sector and power:
on attack, the Hive is launching a wave of energy, then the resulting damage to enemies is calculated from which part of the wave is actually collided with each enemy.
In a week I've built the prototype to test the idea, but unfortunatelly it turned out to be not so convenient to play on a mobile device.
