Doom Loop - Prototype

This is an alpha test, pre-art.  The game loop will change a lot based on feedback and progress!

• Click the portal to get energy; use energy to buy buildings and upgrades that increase energy production.  Accumulate energy to press the fire button.
• There are 4 games in a run, each with increasing requirements to stabilize the rift and advance to the next game. 
• You carry upgrades of buildings and clicks to the following games in a run. 
• If you fail a game in a run, the run ends and must be restarted.
• The more you use or buy something, the more it upgrades. (Clicks or buildings)

While you start anew in each game, you carry some upgrades forward, causing a rapid snowballing effect.
