The game is cute, but needs a lot of polishing. Here's what I think you should improve:
-the enemies, they're slow and a bit buggy, so they're often an easy target. Also consider giving them weapons as well, it will make the game harder, which I think it should be.
-the pause with the dialogue: while I was talking with the red hedgedog and pressing "next", the gun was shooting. That shouldn't happen, I'm sure you can fix it.
-the mechanic of switching hedgedogs should be improved. you probably intended it to be something helpful for the player, instead I found it hard to handle in that section, because the boss would ignore the character I'm currently controlling and go after the other, causing the battle to be a bit messy. That's the most difficult thing to fix honestly, so don't worry, I still appreciated the effort and found it interesting.
One of the things I liked the most was the dash: having such mobility in this kind of games is useful, and you did a great job in this. Controls are fluid and the idea is cool. Hope I was helpful, keep it up.
