Actually the game is kind of fair for what it is , which is a rather poor version of Raptor/Tyrian 2000 -
That said then I think that the game needs better customization options for settings, including ability to turn off music without turning off other sound, custom keyboard settings option , and last but not least a sensitivity setting for the sideways movement , at least sensitivity for short time key press to allow to better position adjustment without banging into side walls or other stuff.
Personally I do not care for the having to manually switch gun when running out of ammo I only find it confusing to have to find out which gun to use...
Game may play better with a controller but I were not in the mood to try that today !

Warships on the Halloween Night is a 2D top down vertical scrolling retro pixel bullet hell shmup. Control a warship with 4 different weapon types (and limited ammo) and shoot warships and evil pumpkins, because I guess those were the only game assets the developers could rip off from wherever.

Gameplay here is on par with the graphics and delivery... extremely bad. They chose to use obsolete retro pixel "art" as a substitute for contemporary PC graphics. It's unclear if this is due to lack of budget or talent, regardless, the overall visual quality of the game is extremely low as a result. Resolution and controls are locked. These flaws push this game far below minimum acceptable standards for PC.
