Uses unholy amounts of CPU making my laptop's fans spin out of control. Editing is very slow, too. Not really a good impression of vim. I'm still going to recommend people to use vimtutor to get used to vim.

Hmm, I’ll look into the CPU processing performance. Maybe it’s the menu animations? And yes vimtutor continues to be a great resource that Braam made. I mainly made this app to gamify learning the vim skills.
