A lot of people are having troubles with the web version. If you like action platformer games, treat the web version as a demo, then play for real on the downloadable version. The itch client makes it pretty easy to manage installs.
Thanks.
(I'm considering removing the web version, since it's causing grief, but I'll leave it up for people who just want a quick peek at the game.)
I'm not sure what causes the crashes on the web app. Might be forward+ rendering on Godot 4.1. IDK.
