This playtest is focused on gathering feedback on the core gameplay loop, including:
overall fun and game feel
weapon and build balance
planetary defense scaling
difficulty pacing
performance and bugs
anything that feels confusing, frustrating, overpowered, or underpowered
This is still an early and limited build of the game, so some content is gated and things may change significantly over time. The goal right now is to make the core experience as fun, satisfying, and polished as possible.
If you play, I’d really love your feedback. There is a feedback form linked in-game where you can report bugs, balance issues, suggestions, and general impressions.
Alternatively the form can be found here.
This playtest is a big step toward the upcoming demo, and more updates are on the way as Planet Killer continues to evolve.
Thanks so much for checking it out and helping test Planet Killer.
