My feedback: This game has some strengths and weaknesses, but in any case it is a completed project.
When I first initially played the game, what impressed me was the quality of the artwork in the title page. Of all the games in this BASIC Dialects Game Jam that I have played, the artwork in this game's title page has left me with the greatest impression. The music also is highly adequate, if not superb. I'm not sure exactly how, but the music fits in very well with the game's atmosphere and genre.
I loved the level of creativity in the design of this game. This was definitely one of the most, if not the most, uniquely creative games that I played in this Game Jam. The way that the story is integrated into the game is excellent, and the "riddle mouths" reinforce the game's story to the player. Well done!
There are a few weaknesses that this game needs to address as well. From the title page, it is not obvious to the user what needs to be done next in order to proceed with the game itself. I actually thought there was a browser incompatibility or that the game had froze. But after pressing the mouse button and several other keys, I discovered by chance that it is the spacebar that causes the game to proceed from the title page. There should definitely be some guidance provided to the user, such as "Press spacebar to begin" or some similar text.
Not to nitpick or scrutinize, but there are spelling errors and awkwardly constructed sentences and phrases throughout the game. This detracts modestly from the game's storyline. And, there's some mildly crude worded content I came across as well, which the game could better do without.
The game itself has pleasing graphics and aesthetics, generally. However, whether or not intentional, the character does not animate while moving, but makes abrupt "jumps" from one floor square to another. Maybe this was the intended effect, I am not sure. I thought while playing that it would nice if the character slid smoothly from square to square, even if not animated. So it seems a bit "clunky" to me, but again, possibly that was by design and not by oversight. The slime creatures move in the same manner, but this might be an intended feature that does actually add to the challenge of the game - I was stopped twice unexpectedly by the slime creatures as I was trying to get across to the treasure boxes, which was a nice feature (the unexpected challenge).
I'm not sure how well or intrinsically the Game Jam's theme "Ruins" was incorporated into the game. Maybe it's just my perspective, but it seemed to me like the theme was not strongly interwoven into the game's content.
I really liked the variety of the tiled graphics in the different levels, from one level to another level. It added to the longevity of the game and increased its visual appeal. Good job!
It's neat to see and experience what the Monkey X dialect of BASIC can accomplish as exhibited in this game. Looks pretty solid to me.
