When the game started I saw some text at the bottom with controls, then heard the sound of text being written out, so glanced up to read it. I noticed the bottom text faded away, and then the top did as well. It would be good to allow the bottom a bit more time, or wait until the player moves, before it fades, especially if you are going to draw the attention elsewhere. I restarted so I could read it all, and even then, the bottom controls text feels like it fades far to fast for the amount of instructional text. Your web page only mentions WASD and E, but this text also has M for Map, Esc for Pause and mentions wall jumps. I did not have time to process all about the wall jumps, but pressing Esc lists the other controls. If you want to go fast, then maybe just mentioning the pause menu having the controls would be good.
On that note, Esc is a problematic choice for web games, especially if you offer fullscreen. It will exit fullscreen when pressed. P is a good alternative for Pause. I'm not saying to completely get rid of Esc, as it is common, just add P as an alternative for those playing fullscreen on the web. I use the browser zoom instead of fullscreen, as not all games like switching out to type notes when in fullscreen.
I started exploring and found some honey up and to the right. I jumped up some platforms, and as I was trying to jump towards the ledge the honey was on, it was as if I hit an invisible wall, while the camera panned over to focus on the honey, and then I fell. I was able to climb back up and jump fine the next time. It is possible the first jump I did bump into something, but the camera moving away from the character while I was mid-jump made it hard to tell.
It seems like you can do 2 wall jumps on the same wall before you just slide down. I'm guessing this was to limit where you can go. Initially I though I was just messing up my timing, and retried several times before feeling sure it was a 2 jump limit.
While pausing to write this (start of day 2) the music started to have a bit of a wail to it that was unpleasant. It made me wonder it an alarm was going off while paused, but I'm thinking now that it is just the music. Maybe meant to set the tone of things going wrong.
I completed the game, though barely. I was interrupted for a bit at the start of the final day, and when I went to do some sections of the timed run I was not quite making the jumps.
