I played this for far longer than I should have. very addicting, from the music to how it feels to mine blocks to how it builds up! i do think the solution that gets you to the end is a little boring but there's only so much you can do here, and it's satisfying to get to that point. i do think the ramp up could be a little bit faster. also, there's a very annoying behaviour where if you have a block on the second last level of the factory (the lowest level you can place blocks), and then a conveyor under it, there's a fairly high chance of getting blocks stuck there. i ended up removing the second last level and that really slowed down my progress. overall, amazing output for a game jam, shockingly addicting and i'm afraid of what you'll come up with next
