>>19390007It's just the kind of game where you have to survive a horde of enemies for as long as possible.
You character attacks automatically, so you collect and upgrade weapons and items so by the time you get about halfway through a run your character is spamming attacks on the level of a danmaku boss.
If you go 30 minutes without being overwhelmed the game ends (with you getting killed by an intentionally overpowered final boss, but still). It's very simple.
