4/5.
It's unfortunate to say but the platforming (more specifically the level design and its pairing with the platforming) is really annoying, I can't put my finger on it specifically (other than saying I have a medically prescribed skill issue), but pretty much every platform will have a death and the game is pretty specific about your movements.
Maybe that's just the type of game it is, maybe it should flow better and afford you some wiggle room, or maybe I should grow some balls and stop whining like an embryo.
I will note that everything but the platforming has a lot of work and character put into it (which is why I bumped this from a 3 to a 4)…but the gameplay criticism is unavoidable and it infuriates me quickly.
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)
