Enjoying this sandbox so far (via the Demo from Steam primarily) and just noticed that the grappling hook can rather easily let you crash the game.
All you need to do is purchase the upgrade, then head near the sky limit on either the left or right edge of the map, then grapple upwards at an angle. You can latch onto a point that seems to be the “wraparound” for the X and Y axis, and if you release too far past the proper corner then the game freezes up entirely.
Not entirely sure how your game is built so let me know if there’s anything I can do to look up/generate some logging/debug info to help – I saw in one of the patch notes that you are using Electron (and I’m fairly handy with JavaScript/TypeScript, though not with Electron specifically) so if it takes some “dev knowledge” to provide assistance I’m cool with that
