Finished the whole game to my knowledge, and it was one of the better platformers I have played (for nsfw, of course) I'm not going to say it was perfect because it certainly wasn't yet I never expected it to be perfect.
I want to suggest a possible navigation system on the "map" since i was confused on where to go sometimes and I do think I ended up defeating the harder bosses before the easier ones.
I also will suggest possibly something to show on your screen or in your inventory to show that you had finished the game so far since I still am not sure if I have finished it or not since I'm still getting "completion 33%" and I don't know if that is referring to this demo of the game or if that would be for the full game yet if a navigation system was added this would also fix that issue.
There was a bug with the "perks" to where you could upgrade infinitely with no points in that tab.
I also would like to suggest faster movement on the umbrella mushroom.
Looking forward to the next update!
