The game was made during a gamejam, so I started working on it about 2 weeks ago! I have school and other projects going on, so I couldn't make a lot of content.
Beyond Prestige XP, you can prestige to get gears, which you can equip onto materials that lets you become more powerful.
"Some upgrades decrease in price every level, some randomly change prices up and down." - I have never seen this bug? With which upgrades did it happen with? Did you do anything special that would cause this bug?
"like spending lots of wood when the charge is above the new target." - I don't understand... Is it the situation of buying new upgrades making wood less powerful making it press easier? If so, then that is intended as that is how I coded the game. Wood is special in this case that it scales with how much wood you have.
"Prestige doesn't reset several upgrades, like wood quality, access to restocker, quantity of wood in the restocker, access to wood," - This is intended, most of the upgrades (everything except wood quality) listed here are not meant to reset. I will indicate this with another colour but everything that is about unlocking will be kept. I know a lot of upgrades aren't in the game yet, but resetting them would feel tedious imo.
Content wise, I am planning to release a new version with some fixes today. And during the weekend I will work on what I intended it to be before the jam ended.
After that I will work on 0.1 which will add a bunch of new content and resources and features.
Sorry that the game is a lot shorter than expected, and I hope the experience wasn't too bad .-.
