Thank you all for the feedback I've received in the last couple of days! I couldn't imagine there would be so much going on in such a short time. I'm thrilled to see that many people have enjoyed the game, and I truly appreciate the feedback from those who didn't. Currently, I'm working on general balance improvements, and have quality-of-life and performance optimizations on the list.
This update shouldn't affect progression much, but it will boost the autonomy and will make things less tedious.

• You can click and drag over machines to refill them
• First Hollow Stone is four times less durable
• Destabilizers work twice as long on a single charge
• Industrial Destabilizers work twice as long on a single charge
• Hell Gem Destabilizers work four times as long on a single charge
• Auxiliary pumps work twice as long on a single charge
• Pump Stations work 1.66 times as long on a single charge
• Void resonators work another two times as long on a single charge
• Celestial Reactor costs half the Beta-Pylene
• Catalytic Preheaters work twice as long on a single charge
• Gradient well description should make more sense now

Have more to come on performance, balance and quality of life.
