I know this was a last-minute pivot to a different game, but you've done well with it. I can see that you've made the changes to keep it all one scene, and you have the system in place to make the spawner start spawning when you want it to. It looks like it's pretty close to being able to add in the shop. If you need any assistance improving on this game or on any other projects in the future, always feel free to send me an email, and I will be happy to help out!
