I am FINALLY back with another lesson today. Space, arrow keys or screen click to move. Okay. This lesson is like a textbook, it has equal lesson and assignment, so take your time. The final assignments, in the section for assignments, are optional, only one out of them is compulsory (you can do more for extra credit).
Note: I've created sprites inside where you could put in the stuff you created for assignments. Use those when you remix the project.
