Hi, there is a map, but it doesn't unlock until you reach the hub. Sorry that you got lost without it, the first part is fairly linear, but I should've enabled the map sooner...
just replayed the game, probably got further than the first time (can like move 5 or 6 blocks at once, stopped counting. got the first 2 ghost upgrades, have an arm and an leg placed).
well somehow got to the ghost hiding in the top, spoke to him.
Well and am stuck at his "why is mum so mean?" dialogue,
no matter what I press (space, controls, whatever) the dalogue doesnt advance. cant teleport back to the hub either as thats blocked during dialogue.
so yeah, am stuck. as mentioned before a save feature would be quite nice. I highly doubt that i will spent another 2 or so hours replaying up to this point again >:-(
Let me know if you ever implement a save feature :-/
