Exitium Scroll

This is my first ever game(mini) after 49 days learning unity, this game is for the game dev and design specialization, the focus is game-play rather than art, and i am a beginner pixel artists, any comments, advice will be appreciated thanks i forgot to say in the how to play: space bar to jump, and build mode blocks have a timer, it is recommended to view how to play to avoid frustration :) thanks
