This was kinda fun! TBH I had the most fun with what turned out to be a bit of a broken mechanic with the game, though: You can fire both spells simultaneously with little lag between shots. So I found myself just spamming both all over the place rather than alternating strategically. Something that could have helped to avoid this becoming broken would be something like a shared ammo system, where you have to cool down before you can use fire, or heat up before you can use cold, etc.
