This was a simple game, but quite enjoyable! The combat felt pretty nice and the warmth/terrain mechanic was neat. I think that being sent to warm up a planet is a really interesting and creative premise. Is the player's goal to warm up large parts of the planet, getting fire powers that convert increasingly larger patches of land to grass? Do the slimes gain new attack patterns and forms to defeat the player's attempts? There are a huge number of ways you could go, and I'd love to see where you take the idea.

The graphics gave me Minecraft flashbacks to getting chased by slimes in caves, which I found funny. Somehow I really liked the hazy gray sky in the game - it gave it this ethereal feeling that I liked, like being outside on a stormy afternoon and you can't see anything.

I thought it was an interesting spin that you can't make yourself warmer at all, making it a war of attrition, like how it would probably be in real life if you were in these conditions. I think having a timer makes sense since that's the only win condition here - holding out for as long as possible, so the player needs some way to know they've made it farther than last time. And I like the idea of having to choose between warming yourself or fending off attackers. It's an interesting strategy. Maybe a third element to that strategy is being able to find warmth, but it's not guaranteed, so you have to choose between leaving your green area to search for warmth or staying in it to guarantee you won't freeze as fast. Might involve some RNG though.

By the way, its very likely that the current build may not work for everyone since I am not only using a third party build of Godot but it was also built on a beta for Godot 4, still let me know if you have issues running the game and I might be able to hopefully fix things for you!
