I really liked this concept! Once I got the hang of things, it was great and fun to explore and try to figure out what I could! A few notes:
1) I got stuck once I got the help sign of the matches. I was unsure what to do as I could not interact with those as I could with everything else. It would place my guy on top (or vice versa) and they would sit on top of each other and sometimes produce a visual bug. I tried a bunch of other combinations of maybe the matchsticks had to interact with something else in the lab, but I could not figure it out. If there is a way to progress, maybe a hint or clue should be added.
2) The sfx were awesome! It was a little off putting when I rested or consumed food/ water since there wasn't as much "pop" as there were for other interactions. I really liked the sound design of the game - I just wish there was more!
Good job on the game!
