It plays nice. Not buggy. Mechanics are well communicated.
Visuals are good, I really like main menu design.
Controls were a little inconvenient for me at first: I was trying to use AD and ZXC at the same time. But then I realized that AD and IOP are way more convenient. So I don't have problem with controls after all. Just that it's not that obvious which schema is better to use.
Honestly, it took some time to understand that I'm not dying randomly, but dying from time exceeding. Mb add some message about keeping track of time on the main character.
It was frustrating that pressing ESC erases all your progress when I just wanted to pause the game.
It's a little frustrating that moving platforms crush you, they don't usually do that in platformers.
It's a little weird that you introduce jumping on the second level, but it is also required on the first one. But it's wasn't any hurdle for me.
All in all, this game has potential, but I'm not sure that time limiting level adds to enjoyment (yeah, it's theme of the jam, but I'm not sure that it's that necessary).
