2D Sidescroller Layout - Jumpin' Jim's Food Collectin' Adventure

My level layout! I wanted to focus on leading the player with collectables that award different levels of points. My only problem is figuring out how the points will reward the player, coding wise.

• The Conflict: You are Jumpin' Jim, a misunderstood antihero. All you ever wanted was for the labs to be trash-free, and by trash-free you're not only referring to old food articles. You need to eliminate reckless students from the labs in order to keep the place safe and clean for others- and find the main source of the outbreak (the boss).
• The Twist: The final boss is actually A TEACHER, whose neglect has influenced the students and corrupted them. He planted spikes and deadly traps in order to stop you, but your revenge will not be sated until the labs are safe once again.
• Where is it?: The Ulla Searing Labs, depicted in background art and color.
• What time of year is it?: Fall Semester, midway.
• What time of day is it?: Who knows? It's in the labs.
• Who Else lives here?: CA students, GAD students, and a few confused freshmen.
• What does their architecture look like: Modern Floridan on the outside, industrial, roof-less buildings on the inside.
• What happened to the environment prior to the player getting there?: It was trashed by the reckless students. You need to pick up trash and collect the points- the more hazardous the trash, the more points you receive.
• How did the player arrive to the environment?: He works there.
