Hey, Thanks
Tamagotchi was definitely part of my starting place for general concept as well as the visuals, so I'm glad that comes across! Building to WebGL definitely introduced a significant amount of lag, I think it has to do with my implementation of the physics in regards to the food - making the room smaller sounds like a good potential workaround for that. Initially I made the room the size it is so that you would have to walk back and forth for a not insignificant distance as a lot of the keychain pet games I've played often include the pet moving from one side of the screen to the other.
I appreciate the feedback and thanks for playing!
