You could potentially do a lot with the running around to manage a few train cars hook, although I found a bit confusing currently.
Some feedback: Might wanna have one button to pick up / drop anything, and one button to use whatever you have (so, the same button to use the water or shoot the gun). Also had some trouble telling when I was shooting guys, or what the state of my water bucket was; might wanna add some visual and sound indicators for those things.
Also took me a minute to realize I wasn’t running out of water, I was failing to keep the engine wet with my infinite water, but that one might be on me.
Cool though, in a minimalistic Atari sort of way.
