Damn, this game was pretty tough. I made it to the second level’s boss (the other gunslinger) before I had to call it quits.
I felt like there were times when an enemy would shoot me either from off-screen or the instant they appeared on my screen, leaving me little time to react. This made it pretty tough to get through parts of the game without just memorizing enemy spawns or just tanking enemies. Also it felt like the sword enemy would hit me after death sometimes.
Outside of those issues, very cool game! Everything feels good and all of the little things like the sound effects and art all work together really well. I appreciated the bosses at the end of the two stages that I managed to see. Nice job!
