I really like the concept and the execution of the core mechanics here. Great job! The 8x8 art is really cute, although to avoid eyestrain I would appreciate some more contrast, or an outline on each of the sprites. I appreciated that the enemies sliding around while frozen.
I would also maybe apply a bit of knockback to both the player and the enemies when they are hit, and perhaps even a bit of hitstun to make that impact feel even juicier. That's something I got as feedback for mine so just passing it forward haha.
