It's like a full review haha. Thank you :) Glad you liked it!
Yes, there is an end to the game, it is quite simple (the character just flies into the white light at the top). I agree that I need to add a progress bar so that the player can understand how close he is to the end of the game. Dash doesn't attack enemies, yes... I was just too lazy to draw another sprite without a sword.
Thanks again for the feedback and for playing!
