Awesome! ^^ I managed to beat the boss!
I too had to restart a few time because of the wall glitch but its no big deal, the game was beatable. You're animations are great I liked the general design of everything too. Some inconsistencies in the resolution (thinking about the background specifically) but again its not big deal because overall it looked great.
Your dash and double mechanics are great, I would love to have seen some more mechanics and bosses. Really enjoyed playing! :)
