Captain Planet & The Planeteers

This is a semi-clone of the NES game Captain Planet & The Planeteers (For reference). It has only the first two levels. I made it in about 3.5 months, on and off, using Unity 2018.3.12f1. Mostly using this as practice, and I learned a lot.
Let me know how it is and, if you're a fellow programmer, take a look at the code to give me pointers on how to improve! Thanks. The complete project is here and the GitHub is HERE
