I feel like most people have said what I'd wanna say, but I do just want to take a moment to say I'm really really impressed with all the sprite work done here. Its really solid and all of the animations look great. The boss is by far the coolest and most impressive of all the sprite work to me, and while I don't understand the hit box of the black hole attack, I won't deny that it is a fantastic visual and just makes them seem all that more powerful than they already are. I love the sfx of the players sword swing as well. For the first few screens I was just swinging my sword around for fun cause I liked the noise until I had to actually stop and learn combat, and even then, it was fun to just dash back and forth across the enemy, doing a quick jab to hear the noise, and repeating until I was victorious. So all in all, really great work here! Great job on making it!

There is a sweet spot with the boss, if you are ontop of the normal enemies you can just dash up and attack for free.  The second attack kind of deals with that, but it only happens twice or so. 
The dash up is an awesome move, but it wasn't intuitive for me and it took me a bit to figure out how to get out of the first hole. 

The background in the dungeon/castle was a little monotonous. 

I really loved the character art and the enemy art. The boss art was amazing and the background for the boss was equally impressive.  Overall I enjoyed it and I hope you keep working on it! 

Ok, I managed to get till the boss. The actual bossfight itself is actually pretty sick.

I love how you also have normal enemies spawning. They definitely kept me on my toes. That said, I think my biggest problem with this game is that you really can't tell whether you took damage or not. Some sort of damage indicator like a sound or screenshake or something would definitely help. This also applies to the normal enemies since it was hard to tell if I took damage from them.

I also thought the actual attack range of the boss wasn't really clear at all. I kept taking damage from his shockwave attack since I couldn't tell how it worked and how I should dodge it.

Still, this game definitely has some cool art and the mobility of the player did feel good to play around with,

Cute game! I am a knight enjoyer and the prince is cute. :-) 

I'm a bit irritated by the movement controls though, specifically the jump button. Since you're using the WASD and mouse control scheme, and the W key has pretty much no use other than deciding your dash direction, I feel it would've been better to map W to jump and make the player's dash direction dependent on mouse direction. Alternatively, ditch the mouse, go for arrow keys as movement, Z to jump, X to dash, would be significantly more convenient. Also, the boss is a bit............ tanky, especially considering how you need to jump-dash to hit them. But I like the little prince. ;-) 

Very nice tutorial. Awesome graphics, gameplay, even controls. Only issue is the view being too big for my screen; but maybe I need to treat myself to a new monitor. I enjoyed the music to begin with but it didn’t loop back.

I think you did a really good job! The platforming was solid and the animations were really great. The final boss was really cool and well done. I think a little more feed back when taking or dealing damage might feel good. Nice work!

Not sure if this is a softlock or not, but I'm unable to really do anything from this point
