Thanks for the feedback sicave! Sorry to hear you had issues with the gameplay, a lot of that is being changed up as I go through it with a group of people who are big into platformers, things such as being able to dash from the ground, more control when you're hit back and a jump buffer to name a few planned changes alongside level design considerations and changes to match that.
That said i appreciate you bumping the rating for the other aspects of the game, and for taking the time to play it despite it's flaws, I hope you can look forward to the full demo which is will be released in a few months (hopefully, never know how it goes with game development)
