The game is really fun to play but i couldn't open this game whatever i try :
Hi Abhas Sinha, this is Gopinath, the programmer of the game. Yes, the wall needs to be dashed into from a distance to open it. There are a few tight bugs due to the short jam deadline, but I hope you still enjoyed playing the game.
Also, please check out the gameplay video uploaded on the itch.io page for a better understanding of the mechanics.
Thank you so much for playing and sharing your feedback!
