Thanks for the feedback. I've heard from someone else that the danger sign could be confused with a platform. Since it appears very early in the level and some of the jumps are trial and error anyway, I kept in. It was more based on what I thought was visually pleasing than a gameplay decision... therefore your critique is valid.
The reason why the game always switches back to the title screen after each Game Over is because I didn't want the player to accidentally skip the Game Over screen. If you died during a jump, with X still being pressed, you'd jump back into the level without witnessing your "death". I also wanted the title screen to still be reachable, basically as an option to start your timer and as a prelude to the level. There might be some other option like deactivating all button presses for 1 second during the game over screen, but then it would take even more time to get back into the game. Btw I just tested how long it takes me to restart after I died and it's literally 1/3 of a second. :D
Anyway, I'm trying to be better with my next project and keep your points in mind. Especially the transition between Gameplay, Game Over and Menu screen.
Thank you so much for playing.
