Thanks for playing.
The crashing is definitely my fault and a regular issue but I decided to upload it anyway because it took way too long to make and I didn't have time to fix it. It's the first time that I've made Unity regularly crash so I guess that's something.
I'm 24 and collected Pogs as a kid (mainly the Pokemon version) but never actually played the game.
In terms of Unity stuff, I didn't use any asset packs (outside of sound effects) or template/demo's but the built in physics and ui systems of the engine are really simple to work with.
