Awesome game! Honestly, if nothing else, I just wish there was more. It ended right around the time I was getting super invested.
The UI took a second to understand. In particular, I hadn't realized that I was supposed to be paying attention to the upper left, and selecting the clock. Additionally, in the first level, the un-selected play/clock sprites looked somewhat similar (with a darker outline) as the selected ones, so I had a little confusion parsing that. Part of me wants to suggest that you should just be going into time selection automatically after every death (since I assume after failure, the player would want to adjust those anyway), but I can also understand if the intention is for the player to navigate that themselves. Still very fun as a whole.
The art and especially the music are both fantastic. The little romantic jingle with the two birds fits the classic toon vibe impeccably. It's a small but brilliant touch, and I feel that it shouldn't go unrecognized.
