You're conscripted into the Planet Keeper Program to defend Earth through strategic defense upgrades and alien combat in this retro-styled incremental game. Balance your resources between purchasing new weapons and improving existing defenses as enemy waves grow tougher, with progression punctuated by prestige-style resets. Best suited for players who enjoy gradual power scaling, light strategy, and a bit of humor alongside their idle mechanics.

A very fun game, easy to understand, with cute graphics, funny dialogue, and a balanced yet challenging upgrade system :) Also, f**k the aliens, good luck trying to not get killed by them

Jogo bem viciante. Ia jogar só um pouco antes de dormir e acabei passando do horário. Trilha sonora foda demais slk.

stuttering and laggin like hell with almost no enemies in the first levels. That is just not good.


EDIT: Fixed fast and works like a charm. Great game so far!

Fixed a bug that caused all upgrades to be obtained when restarting the game. We are also aware of a bug that causes lag on some computers. We don’t know the cause of this, as we haven’t experienced it in any of our tests. If this happens to you, please send us an email with your computer’s specifications and a video showing the gameplay so we can identify the source of the lag. E-mail: robohumanstudios@gmail.com
