Thank you for your feedback! I can feel the struggle that it may be for new players to get used to the side view rather than the common chess top-down view. We've opted for a side view following one of our inspirations for this game, Mewgenics.
As for the minigame being too hard, i understand your struggle, we've seen in later playtestings that it was becoming an issue, but didnt have enough time to handle it. For now, the best way to help with that is getting a trinket, "Broken Metronome" slowing the heart cursor's speed down by 15%.
We hope to continue working on this game if we see that people actually like it a lot, and we will address all of the issues after the jam period ends.
Love your game and your artstyle btw! Hope to compete with you in the finals ;)
