No difficult puzzling needed. If start outside, the 'puzzle' will be how to get into the tower. Everything inside will be buttons, levers, or pressure plates and some structures that move back and forth controlled by the inputs.
As this is the first level, there are a lot of mechanics to introduce as a baseline. Still, this might be too much and need to be spread out among the starting levels.
When interacted with, sends one pulse of energy to output. I think the pulse should last 1 second.
When interacted with, toggles whether it sends constant energy or nothing to output.
Sends energy to output when some entity is directly above it. Maybe only some entities are heavy enough to power it.
Only opened while it has energy and will close when it loses energy.
I'm picturing this as different to a locked door that opens with a key.
Moves from one set location to another set location when powered.
I'm imagining slow movement but fast movement is fine. If we don't want the blocks to move outside of the tile grid, then they could be instant but this might look odd.
Nothing too puzzley. Just have to show how the inputs interact with the outputs to get to each consectutive room.
Since the bow is being introduced in this level, I want to show how arrows can interact with buttons or pressure plates.
