Need a bullet-hell shooter fix? Indie developer Gustav (GuwangeDash, Odd Mobs Zero Arrange) has released DoTonPachi Maximum 1.5, a vertically scrolling shoot-'em-up that pays tribute to the DoDonPachi series.

Many of Gustav's previous works have presented variations on games originally created by prolific arcade shoot-'em-up developer Cave, and this one's no different. Just be warned that you're probably not ready to face the true last boss (seen above, and newly added for version 1.5).
