Hope you can bear with me, I often get verbose :p
Feel free to not take all this like a task list and only note a handful of these.
Didn't figure out quick that I need to use E
Repressing E restarts the dialogue, unintuitively
And I REALLY did not expect the mouse control to swing the hammer
The player's hitbox including the head felt unfun because of the perspective
The boss dissolving effect is really cool!
The pixel art cutscenes were neat! In my eyes, this was THE star of the game. Those cutscenes had a lot of effort in 'em, they looked hype
Jumping towards the mine before beating the boss made me laugh. Accidentally died there :p
I accidentally quit the 3rd, maze castle. Cowabummer.
The key in the castle appeared in another room.
And sometimes the 3rd boss couldn't be hit
Overworld walking is a bit too slow, especially when coming back home.
Unique music, me likey, mostly the outdoors theme The amount of unique ideas in the music tracks was nice.
Some BFXR/JSFXR SFX are super recommended, those are hype.
The bosses were a bit too easy, despite how difficult it was to understand them.
Killing the bullets gives HP too easily, making all fights mega easy
The warlock was a bit underwhelming, I'd add a phase or 2 more - But I loved the presentation! The sprites in the fight look dope.
