The scattering “撃破” text and the map display show so much thoughtfulness and playfulness for the player. As a native speaker, I understood everything, but it actually made me curious to see the game through the eyes of someone who doesn’t know Japanese! (ツ)ノ
Just a personal observation, but the overlapping layers made it a bit hard to see the content. Moving them into a dialog or isolating them might improve the design even more.
Whoa! The attention to detail is stunning, even down to the page design. Hearing that Game Boy boot sound brought back so many memories, and the music is absolutely fantastic! (ツ)ノ
I really loved both the character design and the gameplay. While the camera following every tile made me feel a bit motion-sick, I could really feel your commitment to keeping the character perfectly centered at all times.
