I played the browser version. Out of 6-7 attempts, at least 5 had these big cannons in them which destroyed half the ship. None of those runs were successful, it was terribly hard to move around on the scattered blocks. Although the concept is interesting and I see how it can expand into a bigger game with story and stuff.

Ah yeah I'm sorry, that seems to be a common (and upsettingly game-breaking) bug with the browser version unfortunately. I'm not entirely sure what Godot did to the code when exporting to browser, but their spawn point is supposed to be at least 5000 pixels to the right of where the ship is currently.
