This is a digging game, reminiscent of classics like Dig Dug. Ore replenishes the timer, while mines and bats deplete it. Ore is also a light source, meaning you must remember where things are as you continue to dig downward.
I made it to level 58 before succumbing.
NavigationAgent is clearly present on the bats. A simple reminder that this is not a smart tool. It gets the job done here, though.
Overall, a competently made game with simple and easy-to-understand mechanics. A contender, for sure.
Come back in January, there's still much more to learn about Godot!
