Recently I was asked about the origin of The Iron Gauntz the MSX1 robot game. The dump is pretty everywhere so just google "Iron Gauntz" and you get one.
Name of the developer is Oops which doesn't sound like a proper company. If this game is Japanese (it does display a Japanese message in the first level) I guesstimate it had been submitted from a reader to MSX Magazine/MSX FAN. Do you know where this game came from?
Gameplay: You control a robot within an all direction scrollable narrow room. Shoot the enemy with space/A button, pushing SHIFT/B button continuously activates fast "mover", ESC displays stats. Go over a white tile to unlatch the door(s) to next level, a purple tile for power up/etc., green tile to add a game information. Levels are fixed and not random generated. I haven't found the final objective of the game.
