Collider was renamed to "Stack Hit" and released in 2018 from memory. This was one of my favourite projects. I just left fulltime employment and was the first release after graduating.. so basically lasted 6 months in industry before wanting to go back to Unity and develop 3D worlds. Stack hit is still one of my go to games, there are plenty of features I could have added. 

I hope the gif's demonstrate that design is iterative. D7 metrics are hard to hit. Can see inspiration taken from animations of cod here as well. 

The game was out on iOS but same as previous projects I dont support iOS if they change a lof of requirements for the store as its just not quick for me to build on android and then submit to iOS. It should be on android but as of March 2021 I am still waiting for a review on some new ad policies.
