Pretty cool and fun, great idea for a like puzzler. I was confused with the control scheme a little though. Should I have been able to just keep holding down a different arrow key to keep the movement going or should it have been only in one direction?

Pros:

• Very nice pixel art style. SFX fits with the general aesthetic of the game too.
• Interesting take on time manipulation puzzles. I liked how you could take multiple moves in a straight line in the same "turn", being able to chain attacks by killing enemies, and trying to line up attack runs on enemies.
• Decent amount of level variety.
• Nice and challenging!

Improvements:

• Add some ambience/background music
• Perhaps some kind of tutorial explaining how the damage system works. That was quite confusing to work out

Bugs:

• Enemy moving over the exit (not sure if its a bug, I could still move through the exit just fine)

Overall, an original take on the Rogue genre with pleasent aesthetics. Nice work!
