Well done on finishing your first game, it's a shame it doesn't seem to be beatable. The idea of these sort of progression abilities is a classic and I was really excited to find out what each of them would do. You may want to check in on how you're using nanites for your models if you are (sometimes they are on by default), those can cause real performance issues if used improperly. The timing of the gates to close during the ice possible make it impossible to finish from my experience, I am left wondering why they close at all. Despite the lag, it's clear you have a lot put into the project, I hope you get the issues sorted, I would love to try this again!
