Thank you, i'm glad you like the game and thank you for the report my friend! They are both knowing issues actually. About the first one sadly i was not able to fix it no matter what i have tried. It has to do with the fact that my "respawn" script places the player where he last standing, in which case is near to the edge of the floor. Then the conveyor belt moves the player instandly out of the floor. The only workaround to that is to remember holding the "direction Left" button when respawning and you will not fall off the floor. I know this sucks but i could not change it.
As about the "no death sound" in cases you pointed out, i thought this is not a big deal. I could change this but it will require to change the whole "wall danage" system, which means i will have to edit every single entity again, which also means a lot of work. Still, maybe i will change this in a future update. Thanks again my friend!
