There’s some stuff about the game Besiege one probably has to find out the hard way at the moment, because they are (at least to me) unobvious, and the game doesn’t tell you about them. So I wrote it up. I consider that the opposite of a spoiler: You should know this to do well with the game.
Elderly people might remember a time when a game came with a written so-called manual which described all you needed to get started. Nowadays, in the times of digital distribution, these have been replaced by in-game tutorials. Besiege does have one, but it feels incomplete to me. Ok, so is the game, of course. So find here what you should know additionally…
Balloon and ballast are supposed to be adjustable, but how I do it?
Maybe it’s just me, but I found this unobvious: When you click the wrench icon at the top and then the item in the 3D area, you can adjust buoyancy (uplift) respectively weight. They can only be adjusted during build time though, not during flight. You need to think of something else to dynamically adjust your height.
I can only shoot all my cannons at once!
Fortunately, that is not true. By clicking on the wrench symbol you can redefine keys for your active building blocks. And when you assign a key for a cannon, it is only valid for this specific cannon! So you could e. g. assign the number keys to 10 cannons and fire them individually.
My wings/cannons/whatever end up in the wrong direction!
There are actually two different keys for turning items. Directions can be changed by pressing F after attaching certain blocks, which is stated in their item description. But others (all?) can be rotated by pressing R when holding them at their attachment point, but before attaching.
