In this game, you move a character forward towards your cursor, and regret buying the snowblower.
I think I could have gone through without upgrading (might even be kind of the point), but if I didn't, I wouldn't have gotten to experience the snowblower. Thing plays like a Reach Weapon in DnD. Keep upgrading it, though, and you get the semiautowin tech.
Not bad as a solo newcomer. As you continue to jam, you'll see yourself shooting higher as you learn more and more about Godot.
