Great game !
I see that you did not use a motor and you use self-made engine. For me it is great as you master every aspects but I am afraid that it could be limitative. For example I had some freezes/lags increasing when the bugs following me and my computer has put himself in "high mode" to manage the resources taken by the game.
Once again, congratulations to make it on your own because it is great, so good submission.
The game is as optimized as possible in 3 days, for more information about where everything is being drawn and how the functionality works you can check the p5js docs here: https://p5js.org/reference/#/p5/draw The game graphical performance is depending on webgl which is directly using your graphic card and all the drawing functions are called inside the draw() method of p5js which will optimize its speed according to your computer resources, basically it means that if your computer needs its power somewhere else, it will slow down my game because the priority is other apps and my javascript app is not on top; also all the logic is written on the server side so cpu is quite resting. If you only open my game and there be no other tabs, games or anything eating your graphic card, your computer will focus on the javascript p5js draw function. You can get the source code from my github and check the client side. Thank you very much for paying attention to qualities like this, I love pro devs like you, Tnx for playing :D
