@oblomov@sociale.network basically, a tower defense game in which you move the tower and base around with waves of enemies providing periodic stat checks.
Unless you are talking about the bullet heaven series, that are bullet hell games.

@bovaz of course there's also a series with an ironic name that has nothing to do with the genre, it would be too easy otherwise 8-D

Any longplay I can check to get an idea about how these kinds of game work in practice?
