I had a chance to play this before but never had the opportunity to come back and review, so im back now and couldn't resist having another playthrough!
This for me is a clear winner, its wonderful to find someone that polish's their work to such as high standard for a minigam, and its wonderful to see. The artwork was fantastic, stylish and thematic throughout. Consistency in design is what sets many devs apart from one another and you nailed the goal you set out. It was truly a joy to be in the enviroments (though the doors for completing the round do get lost and dont stand as much as I would like).
Controls were okay, good enough to play this game and enjoy everything it has to offer. Whilst I am not saying your controls are wrong or bad, it merely came down to preference for myself. I believe you did great and you can't please everyone. Jumping and falling off ledges was a great feeling as the animation was unique for each action, I especially enjoyed the blue trail you left behind.
Tutorial and instructions were clear and the levels were varied enough for a diverse experience, fantastic work for the polish AND getting a decent amount of content in too! Would have loved to see the timer a little less punishing or 'close'.
Fantastic Work!
