Not great but nice game. Has the energy of a newgrounds or cereal box game from the basic gameplay and budget graphics that I find really endearing. A bunch of the steam reviews mention they played this when they were a child and that just feels kind of sweet, like this is such a "played on my Dad's 2005 Windows XP computer, where the only other games were Lego Island and The Sims" type game and I like that.

It also doesn't feel like its wasted too much of my time. Other similar games like Vampire Survivors will advertise itself with "Over 50 hours of content!" but I think this kind of mindless, number go up gameplay just gets depressing after a few hours and I reached the end of this game's campaign just before that feeling was setting in.

i got it for 39p on steam and it's called 'Alien Shooter' that kind of sums it up honestly
