A fun little short game. I did not expect only one level though, but the ending is cute. Congrats on finishing it though!
This has "educational" written all over it xD, though I can see this game being much more complex and difficult in the future.
I also understand nothing of the gameplay. I just turned knobs and levers and suddenly the game is done. Maybe add some sort of timer that ticks down once you get to the required goal, something like wait 3 seconds after reaching the goal to fully complete the level. This is just to make sure the player didn't randomly complete the goal.
You took the theme in a chemistry kinda way. That's interesting.
I like the design of the chef guy. Looks innocent but also intimidating.
Audio is kinda lacking during the gameplay, but unfortunately I don't have any other suggestion for this. Maybe add some sort of sound when the player turn the knob or lever?
