I liked the take on the theme, but I was confused on what to do. I didn't notice I could interact with things on the first scenario, and as the other comments said, not being able to rotate in place makes this really hard. I think that could work as it's own mechanic but right now it seems more like an oversight.
I know what bulldozers do, but not the like, cylinders. Spraying water also didn't seem to do much? It felt like the only real solution was to bulldoze the area. It was also hard to tell WHAT I was going to interact with.
This is a good idea that needs work to make it fun to play. A solid base here though.
Edit(Just a short while after)
I managed to beat level 1, and it was kind of fun to plan out my attack plan, and put the bulldozers in the right place and use the sprinklers to keep it at bay long enough to do their jobs. I feel like there are some mechanics here that aren't being well conveyed to the player. It's a good idea, I like the idea of forming an attack plan to keep the fire away, it's fun.
Edit two. I thought I beat it. But then the fire jumped over three bulldozed areas. So, I don't know what the solution is.
