Around 3 hours 31 minutes to beat. This game has unlimited continues and starts you back at the beginning of the stage you last got to. You have a health bar and 1 life before having to continue. Theres some challenging stages and an interesting mechanic with a sword that destroys bullets and alot of unique camera angles, gameplay twists.
I show the game over / continue screen at the beginning of all the stages I had to restart, only showing the fresh life on a successful playthrough of a stage. This game does not restore health between stages, so its usually better to suicide for a fresh start on a level.
This game has no information or videos online that I was able to find, so these may be the first. In this tutorial I break down all the strats I used.
