Heh, regarding Nchiren - I was initially writing it as a question if it was intentional or not and if it was to give the player some indication that they are allowed only one purchase. But then I deleted it to keep my "essay" shorter. Using the same slogan texts as the other vendors ("shop till you drop") also doesn't help to highlight the difference.
The legacy pylon activation on the tutorial level definitely not a priority.
The multiple pylons thing - to me it would make sense if the pylons overwrite the existing gem. In theory there could be a case where 3 (or more) pylons touch the same tile. It is definitely more simple to just pick 2 of them and ignore the rest but ... on the other hand ... if each of them activates but only 2 remain, it would be more fun 😇. An example: if there are green, red, blue and orange pylons (corner position), if you are lucky, your placement would get you healed, place a blank tile and have blue/orange left on the tile. The order in which pylons activate would play a role in deciding which 2 gems remain at the end.
Two minor comments I forgot:
- I notice a significant delay between the moment I place the last possible tile and the moment when the thunders start. It could be something that you added intentionally, based on previous comments. If that is the case, I recommend including some indication for players that they are having 1-2 seconds to drink a potion. Might not be obvious to newer players and would help to show that it is intentional and not just sluggish. I personally would enjoy the reminder as well.
- Not a sound designer myself, but my first impression from the pylon's sound effect was not pleasant. I am getting used to it, but if more people mention it, maybe you can find a more chill / less jarring variation for that sound.
