Thank you for the well structured and detialed feedback! Also first time I hear someone modding Wender, which is very awesome to hear!
I pretty much agree with everything you pointed out, some things I already realized right before the update but decided to stop polishing and just put an update out, other things I've also heard from multiple players, and a few things like the inconsistent spawns (especially for Peekaboo) and really good QoL ideas noone else has pointed out yet.
I made notes of everything you mentioned though and I'll try to address most of these by the next update.
The only thing I'm not really sure about is the "secrets to be found" part, since I want the world to feel interesting and mysterious, but not make you lose out on anything significant if you decide you don't want to explore every nook and cranny (it's a pretty hard thing to balance I feel, and I know I already messed up on that in some parts!)
Also, if you don't mind me asking, how did you mod the game? I'm guessing you don't mean CE, but instead unpacking and editing the .pck or something?
If so, I'd love to hear if there's anything you think would make modding the game easier. Moddability is kind of a far future topic, but it'd be great to know if there's any simple considerations I could handle in the codebase to make it simpler for people for the time being!
