I don't wanna be rude, but the real problem of your game is your adamantine will to not let us play it.
I've reached the third set of rooms this time, but only thanks to your help given in the stream:
- I agree that the normal setting for mouse move>attack is too high
- The secret health powerup it's so invisible that it hurts. I don't even know if the red aura you can see through the wall is intended or not. But even if its there to help you, the secret button to open the door its a mechanic never explained, and its the same damn color of the wall. As you saw in the stream itself, even if you know it's there it's hard to find.
- This powerup is a layered problem, because after we activate both levers downstairs you lock us off the health station and save point. So its vital to continue. By your design, we need to fight: a lancer skl, a projectile shooters, 2 proj shooters, a zombie + skl lancer AND a life or death platforming section in a row. That's unreasonable, I know its not the first level of the game, but then please please make a demo of something that can be a first level!
I was filtered by the last jump of the platform section, (I tried 5-6 times before giving up) dunno if you have coyote time or not, but the real problem are the death spikes.
