Thank you for the feedback. I agree with most of it. At the moment I don't know anything about effects and screenshaking, and of course the game suffers from it. I plan for my next project to learn more about them.
With the spike section I feel like I'm discauraging the player to use it in the right way. The health bar makes it more confusing as well.
I'm genuenly glad for your feedback, because a honest critique can highlight a lot of things I never taught about, like the lack of challenge can be a problem. Thanks :)
