I thoroughly enjoyed this. I played the entire thing from start to finish. I didn’t want to stop. Since it was so good, I’m going for critical feedback only, as everything overall is just very good.
The walljumping mechanic is not always consistent, and of course, the overworld is, while serving a wonderful purpose, lacking and jarring as a swap from the game itself. The sound effect for jumping did get annoying after awhile as well.
To be completely honest, however, this was about as close to a 5 star rating as a game can be without being perfect, so great job.
