I played your game last night on stream as you are already aware. However, as a courtesy to all the featured game devs, I always include a written review since sometimes my thoughts may not flow very well when live (not to mention the alcohol involved while live may impair the clarity of my words.)
Overall, for a game jam game, this is a really great game! Your commitment to CGA-styled graphics is really impressive. Mechanically speaking, it is functional. The game would benefit from having an in-game tutorial to explain how combat should flow, rather than relying on the store page's description. I think another real shame with this game is that there is no purpose for exploration, especially when the game is supposed to be a "labyrinth", it's a shame that events and upgrades are scripted and must be completed in the specified order. I think it would benefit the game a lot if you encouraged exploration, which would help break up the monotony of doing fight after fight, while also being consistent with the game's core premise: a labyrinth.
There is potential here. For a game jam game, this is good. For a full game, it has a long ways to go. I look forward to seeing what you do in the future.
