a few suggestions after playing for a while:
1. allow the player to get multiple drinks in 1 go (maybe an upgrade that increases how many drinks you get after the first dispense)
2. add a delay between placing a drink in the shop and it becoming buyable (these savages will grab my entire stock before i can even set the price)
3. add combination hints
4. add a setting to automatically skip the dispensing animation as present in 1 and 2
5. add a setting to skip death scenes
i know the game literally just released and some of these could be planned but im just putting my feedback
