I know this doesn't make you feel any better, but the movement was made very clunky on purpose, so it's by design. Not everyone's cup of tea, I'll admit. Especially with all the faults in the gameplay.
The blue enemies are designed to force you into either strafing shots, taking your time, or luring enemies into more open areas where you have better movement options. Though I admit, they are maybe causing way too much damage. I already took it down a notch or two previously, but clearly it wasn't enough.
I agree with you about the Stamina. It's way too punishing and I should have added a change to how much stamina you're expending whenever you're doing things when playing on the Easy difficulty. Also the water balls spat by the blue drakes wasn't supposed to drain as much of your stamina reserves as they currently do. I forgot to change the value.
The healing from defeated enemies is also too little for if you play on the Easy difficulty. Something that needs to be changed.
Sometimes when you endlessly try out these things over and over while building the game, you can lose the sight of how difficult or bad some choices can feel to somebody who hasn't been testing the game countless of times over the past few weeks.
Your feedback is appreciated.
Thank you for playing regardless!
