I love this. The concept of each bullet type having its own mechanic is really well designed. Though, I find I didn’t use the green ink as much. And it was difficult to nail the yellow ink strat, but once I did, it worked wonders. It would be even crazier if you expanded upon this and were able to mix ink together. Cyan and magenta make a slow poison pool, or yellow and purple makes an explosion when dashing into it.
Overall, I had a blast playing this.
