Oh my god, this was amazing! The mixture of dungeon crawling controls with typing in black and white makes me think a little of Cryptmaster (Given that I liked this, maybe I should go give that a try...)
Firstly, the fact that you did this in just two weeks is incredible. It took myself and my team (of maybe 3 - 4 others) four whole months to do our project! (Though, there were a few times we were held up for a few weeks due to 3d art asset issues, but still.)
I loved the visual style, the mixture of halftone photobashed (or what appeared to be photobashed) enemies and entities, along with the color-inverted illustrations, and the simple, blocky, digital layout. A couple of times I thought "yknow, it'd be good if this game had-" and then the game would come along and do something similar right after I'd thought it (health crates, multi-word or number combinations that you needed to get right, etc). The sound design is excellent as well! Very textural and crunchy.
The only issue I had with it is that, to exit typing mode, you have to press the Escape key - and as I was playing it fullscreen in browser, it kept kicking me out of full screen mode! >.<
But aside from that small gripe - this is fantastic. Best thing I've played so far in this jam!!
