I really love this genre so I'll try to give an honest and fair review. In spawn after death, there is a fade in transition. Maybe the character shouldn't be able to move until the fade-in transition ends because there is an area (where you get the shotgun) where if you press forward while in that fade-in transition, you'll dead die from the spike before you see even your character. The control for wall jump is not too intuitive; I’m not sure if it is shift+up or shift+right but I think it uses the charges of both wall jump and dash (I’m not sure) Maybe changing the control for it same to jump might help. The spikes where you get the wall jump doesn’t really help to learn the skill since if you fail to use it you die and do everything again to get it. Also, when you drop from a ledge, the double jump doesn’t work. I also noticed the gravity of accelerates the longer you fall, making the character fall off screen when you fall on high ledges. Maybe giving the gravity a fixed speed will help. For the layout of the map, some platforms that block your jump then drop you to the acid are more frustrating than challenging. A shortcut for the weapons would be really nice. Like 1,2, and 3 button to switch. I think it would help if there is a vision around the character for the enemies because the flashlight does not really help see when the enemies are next to the character. Overall, I see the vision of the game trying to give a new take on the side-scroller. I hope this help to make the gameplay feel a little smoother.
