The game is very fun, the only issue I would say is that the whole "counting down the numbers" doesn't really add anything to the game. Apart from fitting the theme, only being able to select lower numbers doesn't really impact the gameplay. I can always just select 0 and then I have all the options available again. I mostly used 0 and then also 1 and 7 in some cases. There isn't really a reason to use any of the other numbers. On the other hand, if you didn't allow the player to go back to the other numbers when selecting 0, you could break the game into levels, where going to a lower number would be a strategic choice. Every level could start with a specific number and have situations where a specific number was needed to go through. That way you have to choose when to get rid of numbers. Then again, maybe you were going for something completely different. The game in nice either way. Congratulations for finishing the jam.
