Gameplay: 

In order to win the game you need to fully power your Core with energy, while stopping your enemies from fully draining it. You store power in your backpack and can transfer it to/from your Core and Turrets.

Enemies will drop energy when you shoot them, but remember - shooting takes a small amount of power from your backpack! If you don't have enough power, you can't shoot!

When enemies get close enough to your Core, they will start to drain it of power! Killing them when they are draining means they will not drop any energy.

In case you run out of energy completely, there are 4 solar recharge station - they will occasionally passively drop energy for you to power your backpack!

Green charge points are connected via a line to a building (the Core, or a Turret). Standing on a green charge point will transfer any power from your backpack to the linked building.

Red depower points are also connected to buildings via a line, but standing on one will transfer energy from the building to your backpack. In the case of the Core, there is a limit on how much power you can remove, to stop you from losing the game!

Powering your Turrets will enable them to automatically attack enemies for you! When activated, a red ring will display the turret's range! The turrets remaining power is displayed in the green bar in its central column.

When a turret is depowered, it will lose its red display ring and no longer fire on enemies. You will need to transfer energy to it to power it up again!

Development

Before starting this Trijam, I realised I could comfortably get the concept out in 3 hours and I was struggling to think what part of my idea would challenge me - until I realised that the "better" version of this game existed in 3D, a medium I've never worked in before.

Cue approximately 8 hours of learning and 12 hours of work on the project later - it took a lot longer than I thought, but I had a great time working in 3D and overcoming the idea that it was too difficult for me to ever make a 3D game!

My main inspiration to take it into 3D was that I wanted diagetic UI for the player and all buildings, something which I was struggling to represent in 2D. Originally the 3D was going to be isometric, but I couldn't figure out a camera easily enough, so 3rd person became the focus.

Overall i'm extremely happy with how the game turned out, even if I went wildly over the 3-hour time limit of Trijam. At the beginning I hoped I'd be in time, but quickly realised that would not be the case!
