Thanks mate! 1 other person had mentioned this issue.. So I'll be uploading a new build within a few days that'll fix this. My idea is to give the player a few seconds of invincibility frames when they first spawn.
Should be all fixed up. Also, there was an issue with some save file stuff, so if you plan to progress a lot further, you should probably create a new save file. Thanks again for the heads up about the slimes!
