My favorite entry in this jam! It’s simple, but has a captivating spark to it, especially in the art style. My only small complaint with this is that the final boss (in the Heart) felt like it didn’t last as long as the others, but Expert Mode did help bring more challenge to it, especially in its final phase. One quality-of-life feature I really appreciated was the ability to adjust the mouse sensitivity mid-game. While some UI indication for the sensitivity amount would’ve been nice, it did allow me to hone in the responsiveness of the controls whenever I wanted (speaking of which, were quite smooth). I also think implementing a way to pause the game and return to the title screen would benefit, especially when playing the executable build of this game. Great work again, and I really look forward to seeing the secret boss!
