All systems and mechanics throughout this project were written and implemented by me, with that being said, here are the ones I believe to be significant:

• Object pooling (I had never done object pooling prior to this project but due to the nature of the project being designed for mobile, having so many enemies spawning constantly was poor for performance and object pooling was required to make the game playable.)
• Enemy creator tool (A tool I made for our artist and designer to have a more swift workflow, just by configuring some stats and drag and dropping spritesheets into my editor tool, simply hitting create would generate all the required elements for a working enemy, after that, simply dragging that element into the object pooling script would add them to the enemy pool to be auto spawned. If required beyond that, some further unique spawning options would be added by myself.) 

I had also started writing an SDK for my company LootGame Studios and had used that during the developement of this project as well, the elements utilised include:

• Achievement system
• Saving system
• Health system
• Leveling system
• General tools (Hierarchy organisation, Sprite billboarding, Singletons, Timers)
