The creator of this game left a gift for lazy achievement hunters. When you are in the menu scene, use the following hotkey LSHIFT+ALTGR+K. It will unlock 24 out of 25 achievements, one every 5 seconds. To collect the last, start a new game and let the enemies kill you by reaching the core within a minute. But if you want to play without this "cheating", the game itself isn't difficult, it's an normal arcade shooter with upgrade progression that will consume some hours.
