To be honest I only made an account to comment on here. First off, well done! Great concept, spooky vibes and an almost addictive game concept of getting random food items. I hope you keep on developing as a lot of people are sure to be keeping an eye on this. 👁️
With that being said, I do have some suggestions for the problems I've encountered. Firstly, definitely the speed at which the food and drink decreases, it's too fast to manage when I want to mutate the character, forcing me to either have her eat different food while waiting for the money to save up or starve her which I believe stops the mutation happening. I think it should go down slower, maybe after a few loops and her consistently eating food it could show she's not as hungry as the start of the game, also the hydration bar being at 0 seemingly does nothing? Though the drinks are rarer than food so that's also hard to manage, perhaps there should be an option to get either food or a drink atleast. Speaking of, as fun as it is, maybe there should be an option to get specific food items if a specific amount of money is put in (eg 111 for bugs, 222 for fast food/soda). This would greatly help save our time if we've seen most of the food already but haven't had all the mutations.
Personally I've tried to go for the healthy ending (ended up seeing her upto when she's a spirit) but due to not feeding enough she reverted back a few stages, which made the progress feel sluggish and I was a bit frustrated. So I've not actually seen any endings despite playing around 3/4 hours, but greatly enjoyed the suspense of seeing what comes out the vending machine next.
I noticed despite how the character looks the people walking past say the same dialogue, hope ones related to her condition can be implemented.
Please add more foods from the scp logs, it would be fun to see some little animations if possible as well. Also, I noticed she doesn't comment on each item? I look forward to seeing the updates :)
