Thank you so much for your help! I'm currently joining the jam and one of the reviewers requested a web version. Now, my game would be easily playable. :).
I'm sure it's going to be very helpful for a lot of others too!
Love your games! (I generally love the villainess manga genre and really wanted to see more of it, and yours are the only one I saw so far) You should definitely make more! <3
