Hi Sentrigal,
Thanks for playing our game! Due to limited time, we only finished designing and implementing these two elements. (But that's the point of GameJam haha, to make as much as we can in 2 days, to devote and enjoy every minute on game development.)
PS: I will continue to make new elements based on the feedbacks of players and my insipriations. Looking forward to sharing with you the new version of our game after the rating period is over!
