No arguments here. I also wanted to get a restart option in, but we just didn't prioritize it highly enough. I think a lot of the poor optimization came down to a poorly generated nav mesh that I didn't have time to manually fix, and and there are also some unrelated enemy targeting/pathfinding issues. We did what we could to resolve it before the deadline, but definitely didn't get it running buttery smooth from start to finish. There's also a massive lag spike the first time you throw the grenade, and we didn't have time to look into that. Fortunately, it only happens once.
Thanks for the kind words and feedback! We had a lot of fun making it and are pleasantly surprised by how fun the game turned out to be (which should be all that surprising since it's basically a RoR2 clone).
