This game was really interesting! Very simple, short but was very enjoyable. I also like the aesthetic of the game. The combat loop was easy to understand but I feel that the exploration was the main part of the game. It was very fun going through the maze to get the item. I actually am not sure if I finished the game extra fast like a speedrun or it is actually the extent of the game. A feedback I would like to give is that you should try add music to your game. The lack of music made this game feel quite empty and dull. The music doesn't need to be long or orchestral, it just needs to be catchy and can be looped. I hope you take my feedback into consideration! Hope you continue making more games!
I'm glad you liked the game! And don't worry, you didn't accidentally speedrun it, that is more or less the entire game. I wanted to add more features (I agree, some music would've definitely been a nice touch), but due to the limitations of Octo and Chip-8, I needed to cram the game's code (excluding map data, sprites and sfx) into less than 4 kilobytes, otherwise it wouldn't work. Unfortunately, I didn't consider music to be all that integral to gameplay, so I chose to cut it.
