Metal drills can now drill through boulders too.

Hah, thanks 👍

Wouldn't it be better to use iron for a seesaw? It feels strange that we won't use it for cutting boards and stuff. 😕

I would not mind having a scale just from rocks and a branch, but some joke entity would be fun. 🤔

A seesaw is not for cutting: https://en.wikipedia.org/wiki/Seesaw It is supposed to be a joke... 😄 Maybe seesaw is a US-specific term? We could call it a teeter-totter instead, maybe that sounds funnier anyway.

Also, in terms of gameplay, I think a comparator should not be too hard to make (in particular I don't think it should require any iron). They come in very handy. You need a comparator if you want to do basic things like recurse on an int (so you can tell when it reaches 0). I also do things like set up a robot to accept harvested trees, and when it notices that the number of trees is over a certain amount, then it crafts them into various products and sends them along.

teeter-totter sounds better, I also thought seesaw was something for cutting stuff :)

OK, done!

The clock will probably end up being an ingredient for other things (e.g. a time machine, see #133), but I'd like to make it a device in its own right. We could make it provide the ability to wait. We could also create an instruction time that gets the absolute number of ticks since the beginning of the game, perhaps. But I think I might do that in a separate PR.
