Found some bugs. Maybe some are intended.
1: English version: dialog text of the introduction story gets out of the textbox. Looking weird.
2: Because of the LttP tileset i expected things to work in some way in the Forest Dungeon. Like jumping off the higher level ground to the lower level, but i couldn't. In LttP you can jump off when there is no border preventing you to jump off.
3: Boss of Forest Dungeon moves before the hero can which caused that hero loses a lifeheart(s) before it can move.
(And i would change the movement speed of the boss to a slower speed, but might be intended this way.)
Second is intended, in the original game it's the expected behaviour (but it's surprising, I agree!).
