This is a really solid game!
The gameplay is really nice with responsive movement and enemy patterns that are easy to understand.
I also really like the theme of "a pixel in an hd world" it's really original and clever.
The only complaint I have, is that the game gets really slow and tedious when you die (especially when it's towards the end of a stage, this is mostly because the combat is very slow)
But other than that this is a great game!
Well done!
