Duck vs Chicken

Merge & idle defense with funny concept.
Duck vs Chicken
This is a mobile game in the genre of Merge Defense Idle, in which a duck launching a missile stops a chicken from entering its farm.
The stage is carried out by merging the missiles, mounting missiles that produce higher damage, acquiring ducks that use various skills, and upgrade their skills.
At first, there were one graphic artists and I (programmer) making it, but now there is one design, one graphic, one UI/UX, and two programmers working on it ahead of its release.
In the early days, we developed the concept of zombie in Merge Mechanic, but to compare various concepts, we tested elements such as CPI by prototyping 7 kinds of videos twice.
So the original plan, the zombie, was abandoned and changed to launch a missile from space.
After that, I continued to try to change the concept from July to November, and I settled on the concept of duck, and it has improved a lot.
I was able to get a sense of marketing by testing various concepts.
