Survivor-type game with boss fights that are more of a shmup style. The visual style is neat along with the music and it's a nice finishable game with a clear ending. But the gameplay loop is mind-numbingly boring. For the asking price it's fine as a product though.
The game basically plays itself as the most basic of twin-stick shooters as long as you pick powerups to form a build. There is some enemy variety but most of them don't change how you play, excluding one or two that shoot or spawn bullets.

The boss fights have some fun bullet patterns but are hardly better than your average shmup boss, so that isn't something that would elevate the gameplay beyond mediocrity. You are likely to turn on auto-targeting so there is no play with the weapons. That turns the boss fights into pure dodging with basic movement.
The bomb is satisfying to use at least, absorbing bullets into a counter attack.

The attempt to be more of a 'real' game than other survivor games kind of just makes me want to play actual twin-stick shooters with better level design and more interesting gameplay mechanics. It's not like there aren't plenty of those with enemy hordes or good boss fights. But again, the aesthetic in Picayune Dreams is nice.
