Here are some problems I found.
-Game runs really badly, I constantly had around 20 fps I would suggest to optimize the game a bit (But I am 90% sure game runs badly because of lumen), and there was a "video memory over budget" message in the top left corner( in unreal engine put DISABLEALLSCREENMESSAGES in console before building the project so it will not show up.forum link

-In that place with first giant broccoli I did not see at all that I should walk past it, I would suggest to maybe make the passage there wider so you can see right away that you can go through there.
-Also you left the ability to open console with ~ button which I used to disable global illumination what make game run in slightly over 35fps
-On those launchpads there is something that looks like debug arrows
-On I think 3 level there was there was part I couldn't progress because I was too big.
I didn't finish the game yet, I fell a bit exhausted by the time I couldn't progress. I will try again tomorrow maybe.
Overall I see care put into this game so keep it up guys. Sorry if I sounded overly negative.
