Hello!
I just wanted to leave my feedback after playing for a couple of hours, but first, a preamble.
In videogames I have two favourite things - necromancy and alchemy. I'm also of the opinion that both of these elements of fantasy are horrifically underutilized. Both, of course, because the elements that I like most about them would often necessitate the creation of a game built entirely around them and not merely have them be classes in something larger... Which brings us to Alchemist, a game built entirely around alchemy.
I think you've knocked it out of the park, all in all. I love the elegance of the system you've presented here. Just enough moving parts to make you feel like your little alchemist is brewing and distilling without drowning players in the nitty-gritty details (Said by one who adores such details in, say, Cataclysm DDA). Additionally I adore the idea that this is a game in which you are intelligent, not strong, and appreciate your stance on preparation and observation being the keys to making it in this game. The lack of armour +1 and flametongue swords that enable me to just run in and eviscerate every last viper in the forest is a lovely and grounding choice. It makes me pay more attention to the world and brilliantly sells the fact that you are just an alchemist. I adore it, and think that what you do have here is brilliant and, again, elegant. The focus on the fact that you are an alchemist and not the generic roguelike hero is refreshing and exciting alike. I read earlier that you want to keep permanent upgrades relegated to tools, which I would also like to gush about, but this is long enough already.
The music in the main menu was excellent for setting the mood, and I do quite enjoy the writer and listener's back and forth while discussing the story. It's personable and well written all in all, though I did want to go through at some point and collect any typos I've found if that would be something you'd consider valuable.
The weather having an effect on the world, the lighting, the graphics easily and readily conveying all of the important information, the intriguing story... I've nothing but praise and excitement for this game and really very much just wanted to offer my encouragement. I'm most assuredly and certainly an ardent and enthusiastic fan, and look forward to buying it the second I see it pop up on Steam. (Stalked your reddit posts a bit, noticed it was a priority for you.)
