Right off the bat, I really liked the menu. The ruffled paper and post-it note aesthetic is really well done! The transition from menu to level is also very cool!
The line art fit with the papers quite well and the game had a pretty solid cohesiveness to it.
Mechanically the game plays quite well and is very challenging. That said, given how exceedingly close you had to get to “mirror” the other side, I got frustrated with this game quite quickly, I’m sorry to say. I’m hesitant to say anything was particularly wrong vs me either not getting into the groove or not having the spacial sense for matching, but there were times the game said I failed where I felt I should have passed… but, again, that could just be me.
Not sure how many games you’ve made in the past, but your description says this is your first ever game jam, and, to that end, this was a very good entry! You should definitely do more jams in the future!!
