Wow! this is really well-made! The art and music / SFX creates a really strong cohesive atmosphere. The puzzle design is nicely paced introducing different mechanics well whilst offering a a developing level of challenge. Really enjoyed playing! My only quibble would be that when I knew I'd messed up on a level I kept accidentally trying to press escape to reach a menu to restart the level, which would then restart all the levels, otherwise this is a really delightful and engaging experience utilising the theme of loop well!
