Hi there, Tried the game really like the music and art work had a really nice retro platformer feel to it.
Only had a couple issues with the game:
1. Either the jump physic or the height of some of the platforms were too high but it many attempts to get on a couple, To the point where it was quite frustrating.
2. when I got to the 3rd or 4th Level (picture below) after spending some time getting the platforms in place and using first ghost to hold buttons, I went to kill my self to respawn a new ghost and no characters respawned at all, Was left stuck and not able to carry on.
Apart from those issues the game was great and I really liked the ghost mechanic and puzzle aspect of the game. Also the difficulty increase between each level was done well and game was very intuitive without the need of pop-ups or tutorial. Well Done!
