Hey there! I just finished playing your game about three times through, and I've got a few bugs/misspellings/etc that I'd like to report.
I'll put these in spoiler tags because some of the things I mention may clue people in on what happens in the game.
1.You can walk under the bamboo sticks in the map with the campfire at the beginning.
2. It's a little difficult to see the message prompts for damage and stuff during battle.
3. If you choose to jump the wall, the samurai you fight in front of the gate doesn't disappear no matter how many times you beat him. He only disappears if you decide to stab him from behind.
4. If you decide to fight the samurai in front of the gate head on, the ninja sprites in front of where the samurai was standing disappears after the battle.
5. It says "We should not leav" rather than "We should not leave" when you tried to walk off the map with the samurai guarding the gate.
6. When you climb up the wall after entering the shogun's castle and try to stab the first guard from behind, he turns around when you press z on him.
7. After you stab the previously mentioned samurai, he disappears. However, if you walk over near where he was standing, you end up fighting him as if he was still there. Like the samurai in front of the gate, you can fight this one repeatedly as well.
8. Additionally, after fighting the samurai you take the armor from, the first samurai that you stabbed reappears where he was last standing after.
9. When you speak to the guard captain in front of the shogun's room during night time, there is a typo that says "were is my bed?" instead of "Where is my bed?"
10. When you ask him where your bed is, he says it's the furthest to the east from here. However, the bed that you can sleep in is the one on the far left. I don't have a compass, but I just assumed the furthest to the right would be considered "furthest to the east" rather than the bed furthest to the left.
11. If you go to the door in the upper left corner after waking up in the shogun's hideout, it asks if u want to hide. This door was not there the previous night.. If you say no, you can then walk through the door and over the wall into the ceiling.
12. Also, if you approach the door again after it has already been opened, it shows the closed door open again before it asks you if you want to hide.
13. If you say you do want to hide, you jump into the door and it closes behind you but the door doesn't completely cover your sprite so the head of the character is seen peeking out from the top. After hiding behind the door, you can, as mentioned before, walk onto the ceiling again. You have no way of getting back to the room because the door blocks your path. As a result, the only way to continue the game is to either restart or walk over to the spot on the ceiling that asks if you'd like to jump down that you used if you decided to climb up the wall the night before to stab the first samurai from behind.
14. When the second shogun comes from behind after you kill the first one, there is a typo where you say "to" instead of "too".
15. After you get to the game over screen, you can still open the menu. In the menu you have Kira and an unknown character named "Spectate". (This occurs if you choose to fight the real shogun with Kira as your partner).
16. The second, real shogun that appears says "to bad" rather than "too bad".
17. If you get the ending where you go against Kira, it says "wery lonely" rather than "very lonely". Also, the text scrolls by quite fast, so it's difficult to read all of it in time.
18. Again, the menu bug happens where you can still open the menu and one of the characters is "Spectate" if you get to the ending with the scrolling text after fighting Kira as the last boss.
19. After defeating Kira, his sprite shifts down and to the right one square before the screen fades out.
20. The map name that shows up after waking up says "shoguns hideout" rather than "shogun's hideout".
21. You can also walk up into the ceiling if you step through the cupboards that are located near the large bed in front of the shogun's room.
22. After defeating the false shogun, you're missing a comma in "ha we fooled you".
23. It says "Apperently not" rather than "Apparently not" when the real shogun speaks.
24. The word "stay" is not capitalized when Kira gives you the choice between staying with him or going to the samurai side.
25. If you decide not to fight the armored samurai in the hideout, you can just walk over to the bed and sleep. The next morning, you still look like a ninja but all of the samurai act like you're in disguise and tell you to carry on.
Hope this helps. Have fun making more games!
