Damn, bro, you got this. I can feel the frustration and happiness at the same time in your comment XD. My goal was to create a challenging platformer for speedrunners, so I intentionally kept some bugs and issues to make it more "challenging." However, it turns out that these elements became frustrating, especially with the replaying of the calm puzzle parts.
I see potential in this game for players like you and me who enjoy speedruns and challenges, so I'll definitely update it after the jam. I plan to add more levels and improve the platforming.
Fun fact: During playtesting, the timer for the 4th level was so hard to match that even my friend, who also worked on the game, couldn’t complete it. but Since I completed it, so we knew it wasn’t impossible, so we kept the timer at 30 seconds. so You’re the first person (after me) to complete the 4th level. You got this, man. Congrats!
