This is a super cool take on “momentum”, I really enjoyed it even though I’m really at a loss on how to beat the slime. I had an awful first run with an ice block almost immediately which took forever. Also, turning was off, not rotating 90 degrees but maybe 75ish. I don’t think it affect the gameplay but was… off-puting.
In case you didn’t know, Godot has 3 renderers, Forward+, mobile and compatibility (default in the top right of the editor). Desktops can run any of them, Forward+ being the most feature rich but web can only run compatibility, and will automatically do so. My guess is you’re using some Foward+ features in the env that aren’t supported in compatibility. If you switch it in editor, you’ll see what web looks like, as well as get warnings for features that don’t work.
