Thank you for the kind words, brother. I really appreciate that.
Yeah, in the full game there will be a save/load and checkpoint system, so don't worry about that. Also, there is a hidden "speedrun" button in the options menu, keybinds page. If you find and click it, it allows you to sprint from the start.
Thank you so much for playing, my friend, I am very happy you liked it.
God bless.
