I think the plunging mechanic is quite fun fun an satisfying but the general controls feel quite clunky. At the start i didn’t realize that my robot can move, so i just tried to get stuff but everything was to far away, but i was also very confused that the plunger goes through the Gacha machine. The next confusing thing was that sometimes i need to put a coin in with left click and sometimes with right click. Also the hitbox for this seems to be pretty small, so it felt like it wasn’t actually working half of the time. Maybe you can have a outline for the coin slot that i can see if i’m over it. Next thing is, that dropping items is not always working, or rather only when the item is in an open space, which feels also very bad, why can’t i just drop the thing where i stand? Lastly, since i can only ever have one item i dunno how i’m able to craft things that have 3+ components.

I think there are just way to many buttons to press for the simple interactions you have going on. It also feels wrong that you can’t move while you have the plunger out. I think you should either be able to move always or, what seems like a fun solution to me, let the plunger also be the way of movement, so you have a multi purpose mechanic.
