It's glitchy, but...
...I still love it. A much longer game of the same type would be absolutely awesome. I love the graphics, the music, basically everything but length and glitches. Oh, and it sort of reminds me of Problem Sleuth. You know:
>Use Key
What key? I'm pretty sure all you ever had was a bazooka.
>Fire bazooka
Bazooka? All you have in your hand is a shiny bronze key.
The itemswitches reminded me of that :3
