By far the most creative interpretation of the theme I've seen! I love how you iterated over the concept and how the game plays like a puzzle game but still tests your reflexes. The difficulty progression feels good, I just got briefly stuck on level 7 because for some reason I forgot you could move and not just dash.
As feedback:
- besides adding audio I think the visuals could need some work, the simple shapes and the arrow theme work well, but a higher resolution and crisp shapes would make it feel cleaner than the current blurry pixel art.
- I'm sure you're aware, but when moving fast enough, it's possible to move through portals without the game registering the collision.
- I would also have liked to be able to navigate the menus with the keyboard, reaching back to the mouse between levels was slightly inconvenient.
Great game all around, congrats!
