This was a fun little adventure. The map was big but fairly intuitive, the save points were obvious, power-up usage was clear, and I really liked the light/dark effect you had going on at the bottom level. The vines dangling around after being cut was a nice touch too, and the enemies being burned by light sound effect was surprisingly satisfying.
Some areas where I struggled:
- I won't mention the stickiness of the wall climb cause everyone else already has, but I found the wall jumping itself to also be a bit awkward. It took me awhile to get used to just pressing jump while touching a wall, I'm used to there being directional input as well. It also didn't always feel consistent, especially after getting double jump.
- The murderous falls at the beginning felt kind of punishing. I get why they're there, but I'm told that I'm supposed to descend and the first few holes I try to go down just kill me on landing. Some sort of indication or warning that these are danger holes would have felt better.
- A bit of a nitpick, but having villager dialog remain on the screen even after you've moved away or changed screens was a little annoying. I'd consider either having the dialog box auto-close if you get a certain distance away (and maybe have some sort of indication that there's more that the villager was going to say) or just stop the player from moving while speaking to a villager (and don't place any enemies nearby). This was particularly jarring in the final room where I was trying to talk to a villager while avoiding a slew of bats (I didn't know the light would kill them instantly yet).
But overall it was a short and sweet adventure. Running through the game felt good for the most part and I never got super lost. Enemies were dangerous but not too difficult, and there were a few touches that surprised and delighted (the vines, the light in the darkness). Good job!
