If you're struggling with the game, you can try walljumping and dashing (with shift) and double jumping and shotgun boosting, if you still can't beat the normal mode, click on the game name in the main menu, and go inside normal mode, presss `, write "up <how_much_up>" ex: up 3000
Make sure to not put a number too high or else the game wont generate the platforms for each area, if you do so, you can put negative numbers into the up command, check out the `command_list`, Also pause the game and look at the bottom right :)
