yes I put invisible walls instead of adding colliders in each grave. but in next update i will fix the issue i having the each gravestone have its own collider so the player can avoid the ghosts in the grave maze.
also for the boss battle, the battle starts immediately and launches 3 attacks at once every 4 secs with a delay. so player has to dodge the incoming fire bullets immediately after the entry animation of the boss 😅
After the fireballs collide with ground, it stays there for sometime due to its lifetime. so you have to avoid the fireballs in ground till it fades away.
sorry for the incovience. i will make an update soon to fix those issues👍
