I honestly not enjoy playing this game. I did at the beginning but I had to stop at the factory.
My main problem is that there are way to many instant death traps and I just don't think it is fun.
Maybe you could add some checkpoints before platforming sections that you get teleported to when you fall into the water or get crushed instead of going back to the last checkpoint.
I also have a problem with the combat. I feel like I'm fighting the combat system itself instead of the enemies. The attacks should have some windup instead of being instantly executed when entering the enemy range.
Also there are some areas where it is very difficult to enter a area where an enemy patrols , because as soon as you leave the area you get swung at instantly.
The spikes should also have some kind of animation before the come out.
Another thing that I think needs improvement is the player collision. It feels like it is a eclipse because you slide down edges. It should be a box instead I think.
The double jump is also weird. It is extremely inconsistent. The height you gain with it seems to depend on when you do it, which makes it very unreliable.
If you could fix all these issues this would probably be a great game, but at the moment I'm not the biggest fan.
