Bugs and general polish aside, one actionable piece of feedback I'd give is to try and inform the player on what the controls are, and what they're supposed to do.
Tutorials are all well and good, but since this is a game jam and we're all stripped for time, something as simple as a UI panel that gets slapped on the screen when you start up the level would be sufficient. Something like that in this game telling me what I can do and what my goal is would have done wonders, since in lieu of that, I just wandered around and picked up a couple cylinders without really knowing what I was doing.
Regardless, this is a solid attempt for a first game jam! I can see the ambition and effort on display :)
