Hey! Thank you for the input. This is the kind of feedback I love so much appreciated! Spoilers below:
1. You can create an autoburner using lava but you need to use the Cryoblaster to freeze it into scoria and cinder. I normally then fill up a few blocks of filters with cinder and then use the Flamethrower to turn it back to lava. When the slag runs over it will start burning.
2. Got it! I haven't really decided how to deal with biomes yet but maybe each biome should have its own sand type and once you've got the tech you can simply automate it away like you say so that you can focus on the new biome.
3. This is an interesting one. Unlike other factory games the belts can be stacked vertically so the actual bottlenecks are normally the launchers. It shouldn't be any problem to make a setup with shakers that can take huge throughput. With that said, faster belts are probably coming.
4. Yes and yes. Both are coming!
5. The full game will be procedurally generated.
6. Good idea!
Thank you again! ❤️
