Really impressive visuals, audio and theme! Love the design of the player too. The concept is really clever where you need to die to get through. I did find the game quite difficult despite the hints and noticed a few things that could be improved if you continue making the game:
The player gets clipped to a wall if you don't make it in high enough. A solution here is to make walls have 0 friction so player doesn't get clipped to a wall. Also you can allow Player to make it above a platformer even if they slightly miss.
Also I found that left and right were too close to the other controls of Q and E. It made it difficult to move, use the curses, jump with spacebar and use the mouse at the same time. I recommend moving the move controls, to W,S or generally finding a way of reducing the number of controls.
Definitely something you should continue and really cool you guys did this in a week! Keep it up
