What is AstroDig?
Imagine a tower defense game where you're actually mining a tiny planet to pay for your guns. AstroDig blends resource management with a strategy shooter on a spherical map, forcing you to rethink how you build your defenses.


Gameplay
You aren't just placing towers and watching them go. In AstroDig, you're running a mining operation on tiny circular planets. The core loop is simple: mine, expand, defend, repeat. You've gotta dig up resources to fund your defenses while fighting off waves of enemies. It's more of a strategy shooter than a classic Bloons or Kingdom Rush experience because you're physically managing an operation on a sphere. This circular layout completely changes how you think about placement since you can't just build a long straight line to funnel enemies.
It's a cool feeling to turn a barren rock into a fortress, but the game has some rough edges. It's very minimalist, which works for some, but can feel bare-bones for others. Since it's still in a playtest/demo phase, it's unpolished in spots. You'll notice the 'minimalist' vibe sometimes feels like it's missing a layer of depth. At $5.99, it's a small ask, but you're paying for a scrappy indie experience, not a AAA cinematic one. You'll need to push through the slow start to reach the dangerous planets where the game actually kicks in. I'd give it a 7/10 right now.

Verdict
Grab the free demo on Steam to see if the circular mechanic clicks for you. It's perfect for fans of minimalist strategy, but if you want deep, complex systems or high-end graphics, you should wait for the full release.
