The version of the itch app I'm using is 25.4.1. I'm currently on Ubuntu 18.04 LTS
The game runs perfectly fine when run from a browser, but if I play through the app is extremely slow and completely unplayable. Which is odd because the game runs perfectly through the app in windows, and the game itself is very light. I suppose there must be some problem in the version of the html5 wrapper used by the app that kills the performance. I think that's the cause because I've never had a similar kind of performance problem with anything else I've downloaded through the app.
