This is a first draft at best. Nothing really gets fleshed out.
Úžasná hra, zábavná! Začínám mít stísněné pocity, pokud jde o osud Země! :-)
Not good. Most of the game is just a barren landscape littered with the same <10 assets repeated. There's no challenge, since the second gun in the game is less than a minute's distance from the start and makes every enemy trivial to kill. In fact, the entire game can easily be beaten in less than five minutes. The sound ranges from acceptable to horrendous. A lot of it feels like it was designed to avoid putting work into design: enemies just disappear when they're killed, dying or winning is instant and just shows a text screen, the three enemies in the game all behave the same (the flying enemies don't even fly!), and the turrets rotate around but do nothing.
This may be the remastered version, but it looks like it still has a long way to go.
