This thread should be titled, "be as vague as possible about a game". I don't really see any shit talking whatsoever.
Here's mine:
You play through a side-scroller composed of outdated pixel graphics, shooting aliens that generally are all the same other than color swaps. The soundtrack is basically just holding down random buttons on a synth, mixed in with cliched future bleeps boops and squishy sounds. The bosses are pretty unoriginal, just dragons of different colors and sizes. Some of the npcs aren't even named very well either, like the "chozo" which basically just means birdperson, because the npc is a bird/person.
The gameplay involves shooting every single thing in a room and hoping to find hidden items that you don't even really need, and going across maps to get keys that open doors on the other side of the map.
