This is a nice, cute, and short game! I played through with 3 increase speed (?) cards and it seemed to go well. I feel like some music or sounds would have paired well with the lighthearted story and stylized art.
Two non-game content related notes-- The game page is so wide that the right side is cut off for me and the game sits awkwardly on my screen when not fullscreened. I almost didn't see the fullscreen icon because a bit of the bottom was cut off for me too. I assume the sizing issue might be related to me using a laptop? I would also like to see the credits placed more accessibly, whether that's a button on the main menu, in the game page description, and/or adding their itch.io accounts as game contributors. To only have the credits play at the end with no other way to see who was involved feels like a bit of a shame, but this is purely a personal preference thing.
I love the textured, child's drawing book art direction and the meticulousness to continue that vibe into the UI and font choice. I like that you played around with different shapes and designs for the pinball-like stages too. The game shows a colored square (black or magenta) in the middle of the screen when "continue" or "normal/timed" buttons show up and I'm not sure if that's some image that isn't loading in properly or what.
The gameplay is simple and leaves open the potential to build on its complexity with different card effects and more time to develop. I would have loved for more player control in the gameplay as I just launch Eggie once per level and wait for them to hit the enemies (sometimes taking a while to do so). This could be in the form of pinball flippers to control or the ability to relaunch Eggie after it slows to a stop, for example.
