For a first game, it’s impressive.

• Blinking background is maybe a bit distracting.
• Great portal art.
• I don’t know if it’s intended as a trap, but some platforms’ collision box are different from their sprite.

As a complete beginner i'd say you did a good job. It has a LOT of room for improvement, and you probably did not make this game with this jam's theme and prerequisite in mind. I wish you the best in your game dev journey.

i rated it, could u rated mine now

That's an awesome game for the first time. Congratulations on starting this awesome journey  (Just remember make game on theme and prerequisite of jam, theme was frog and other than jumping there is nothing froggy in your game. Prerequiste was mouse input only but your game uses keyboard input)

why not html5 😭
