Strangely enthralling, for something with very minimalistic graphics and no animation! Everything works out in a pretty logical progression, and it doesn't require that much backtracking! I kinda wish you could roll over your inventory to see what you do and don't have, though, or at least have the uncollected items be darker for a better contrast. I also think that, if this game were updated, NG leaderboard functionality were added!
Bug report: Upon starting a second game after completing the first, the camera did not work as explained in the description; rather, the arrow keys moved the camera instead of the player. The leaderboard also doesn't work at this point, which is why I figured NG leaderboards would help.
