Hello.
I am writing to you about the bugs I have found in your game.
Minor bugs:
1) The ghosts get stuck inside columns and water. They eventually get out of it but it's definitely not the intended behavior.
2) One of the first 3 boulders (those near the lever) generates a boulder of its own, I'm not sure if it's intended or a bug.
Gamebreaking (or close to it) bugs: The ghost near the save point doesn't have a timer.
After the first fight it will keep chasing and triggering battles.
You can try to run away to avoid it but you can't avoid two fights in a row.
The battles. They seem to be chaos-based. There is no valid strategy, everything is left to chance. Gaining and losing MP seems to be totally random, making the fights quite dull and unnecessarily repetitive. My advice on revisiting and reworking parts of the game comes from the fact that the underlying idea is nice but not well developed, in my opinion.
