The game is pretty interesting. I am amazed that you can turn Scratch into HTML. I thought I knew quite a lot about Scratch lol. I found the gameplay to be a bit ... stiff. There wasn't really any story from what I played. The intro to the game I can only describe as "the horror". It is pretty creative in a sense. I don't find it to really capture the essence of the theme, I guess you could say it is a garden but from all I know it isn't secret. 5/10 experience.
The bindings being the arrow keys is a little off putting, only reason I knew to try them was that I am a Scratcher lol. The intro gets quite annoying. Restarting is also a bit annoying. The player is put into action way too fast. The sounds are a little too loud. The player seems a bit too fast, it is hard to control because you get stuck on the walls (which I assume is because you couldn't fix that, been there). A description for the game would be sooo helpful.
The game seemed a little too hard before, but it seems like more of a healthy amount now. The fact that you use scrolling and brought a Scratch game to itch is a bit praiseworthy for technical abilities. The art is cool. I'm sure that you will make a great game dev someday if you keep at it.
