Enjoyment - A rage platformer + a metroidvania is a cool idea.  It might be cool if after you pass a section the fake tiles disappeared.  Would help with back tracking n stuff.

Execution - Very good start! The character feels a bit heavy, but can be fixed with some tweaking.

Visuals - Nice pixel art! Making some more ground tiles would help it look less repetitive for sure.

Audio - I can't remember the sound much... (only foot steps?) this free sound maker is great for retro style games/proto types if you wanna add more.  https://www.drpetter.se/project_sfxr.html

Metroidvania - The lore seems like an awesome idea for a Metroidvania!

Keep it up and good work! And please check out my game when you can :D

I want to start by saying the game looks great, the lighting is pretty and makes the world feel enticing and somewhere I want to explore.  The player controls well in my opinion.  To contrast that my experience was pretty rage inducing(which is intended by your description) and I didn't make it very far before rage-quitting.  However I know that rage games are not my favorite so I may not be the target audience.  I just wish there was *some* indication of the fake blocks being fake, or that there was a powerup that gives you that indication.  Also, not sure if this was intentional, but there was music when I started the game but it stopped when playing.  Regardless, its a pretty game and has an interesting backstory!
