Been waiting for BastionOS ever since I tried the demo. It’s a simple but seriously addictive little game, and it gets incredibly satisfying once you expand your arsenal after the first few initial levels.

I haven’t even seen the quarter of the skill tree yet, but even at my current playtime it already feels huge and offers a ton of variety, from giant laser beamz to flame patches to cluster bombs lol. There’s something incredibly satisfying about watching the whole screen go kaboom after a well aimed shot.

Would honestly love to see an endless mode added down the line!

Glad the game finally came out. There is something weird about chilling while enemies are approaching with increased pressure. The feeling of progress is always there. You can take it slow or rush, completely up to you.
I like the math behind this game :o
