Okay, that intro was pretty funny. For a game made in seven days, it's pretty solid - it'd definitely need polished up for a full on larger project, but what you have at present is a nice solid foundation for an arcade game.
I've never played vampire survivors, but from what I've seen this is a similar kind of vibe to what it goes for - endless enemy waves, with the focus being on movement and building up your skills and ability sets to see how long you can go for.
My only question is: what the dog doin?
