Thank you. Glad you liked it :)
The money node is a real bottleneck because i just done it quick and dirty as rigidbody2D so it would just collide with the walls and stay in bounds. then at some point you have like 2000 rigidbodys with square collision boxes on screen in browser and the result is 0.25 fps :D
I had ideas to optimize that and also add upgrades for easier money collection but there was not enough time left.
