Thanks for the comments, I really didn't expect anyone to play this, let alone want to download it. I've made lots of changes to the game based on your suggestions since yesterday:
Updates:
- All chests are now only openable once
- Entrances / exits in areas made more clear with paths and carpets
- Enemies are now in sideview during battles
- Added some battle backgrounds to different map locations
- Gave the main character an actual name (oof this one's on me, I thought 'Main Char' was just the variable name)
- You shouldn't be able to walk onto walls / objects anymore
- Removed most random encounters (there is still one but it's in a very specific region)
- Balanced out the combat between enemies and main character
- Fixed the double attack skill
- Removed confusing cave in basement, it was just decoration
- Added some objects you can walk up to and it will show some text about the object
- The game has multiple endings!
- The outro cutscenes explain the story a little bit better
- No more confusing 'game over' endings
- Enemies that roam around the map - some are passive and will just wander around, and some are aggressive and will chase you. Interacting with the triggers a battle to start. They will respawn after a while to keep the game's difficulty up.
- Some people asked about a downloadable version so I added one as well
