Very interesting!
I am glad to have unearthed this interesting submission because it really is quite good. The best thing about it is that it really works well as a puzzle game. You have to look carefully in the lower hand corner to know what is going to come next. This is a game that is great for forming strategy. It might take a few deaths, but it is so unique it truly is worth it. It could have been a bit more detailed as it did not have a background, but still good.
The music is so mundane and it really contrasts with the more complicated gameplay. It was not too hard because you did not have to be on top of a platform to go in the door or get the key. That is quite a big key. This may be the first game I've played here where the description was three different game genres! It does well in every one of them.
