Nice game!
The controls are easy to understand and the game is pretty addicting. The dopamine rush I got from winning (even though I was really slow) made the game feel very challenging yet rewarding.
I think your take on the theme is very creative, and the game design is done very well.
The art for this game is pretty good, and I liked the font as well as the giant hot dog hanging in the background.
I might be wrong about this, but it seems that after the player successfully eats a hot dog, it doesn't really show in the game, only the counter goes down. (maybe add an eating animation/munching sound?) Additionally, I think the three competitors look really funny (especially the middle one) and it adds a lot to the game.
For the sounds, I like the background music, and even though it's a little intense-sounding for a hot dog eating game, I liked how you turned down the volume of it so that it fit better. The coughing sounds were a nice touch too.
All in all, this is one of the best games I've come across and one of the only games that I actually had fun playing. Good luck in this game jam!
