Pretty cute game. It does feel unpolished, but that's understandable-- seems like you're trying to do a lot with the mechanics. The character switching with the hearts is still a little confusing to me. The game has quite a charming vibe-- reminds me of Super C and Zelda 1. The boss dialogue was pretty fun, and the music was pretty nice. But yeah, like euniworm said, it feels like there's no reason to kill enemies when you can just dash right past them and beat the game super quick-- they're generally just not dangerous enough, I think.
In short, it's like a big sloppy kiss-- good in an indulgent way, lacking in elegance, but that doesn't matter too much. Yeah wow great simile there mhmm
