Very impressive entry considering you lost a whole day to a power outage, nice work!! The artstyle is very cute I dig it, especially the little Italian flag above his head that turns into a glider. The movement has a good amount of depth to it with the momentum system and glider controls, I think there's a good amount of room for skill expression which is cool. Sounds are great and its awesome that your brother and dad helped you with the project, love to see it!!
A couple of minor critiques: (1) spikes are kind of hard to distinguish from the background, they could use a little bit more visual contrast (2) the camera lags behind the player movement a bit so sometimes you die unfairly, I'm not sure what a good fix would be, but maybe try zooming the camera out a bit? (3) the black text on the dark green background of your itch page is very hard to read, maybe try a lighter font color
That being said I really enjoyed my time with your game, it has a lot of charm and personality. The movement is super slick. Cool entry, and keep up the good work!!
