Awesome game
It took me a while to get out of the caves since the last disruptor was way up and you had to place the lift exactly at the right place to get to it (an awesome commenter made a map which helped me haha). Finished the game later too, (2,40 hours of playtime)
Its just a bit hard to cramp every defense together with the right power, that's where I got an Idea on how to make it better! What if you could connect the energy accumulators together to make a crude "power-line"? I think that would be great!
Also, I think it would be neat to add an immobility option which can be ticked on or off where if you surpass your maximum you can just dump the power (hold w) to get walking again!
