Frosty & Richman, I loved this concept probably one of my favorites as far as really sticking to the theme and making the best use out of the theme. The different types of shooting/die made it very fresh to play always. The different types of enemies also helped keep everything feeling new all the time. I think this is so important because a lot of games can feel really repetitive and you had a simple game and maximized your use of mechanics to make this game fun and always feel like something new is happening. This has given it tremendous replay value.
I think as far as working on something, the gameplay is solid but the art lacks a bit of consistency. The enemies felt a bit separated/ like they were from different games because of the art style-shifting a bit drastically on them.
Overall mega solid game, great job and I look forward to seeing more!
