I'm going to be totally candid with you -- the general, publicly stated, distaste for the fact that you used RTP for a jam-style contest, coupled with the warning / "dev's note" at the beginning soured my opinion right from the start on this one. As long as it's used correctly / well -- which you have mostly done, but we all have minor issues in short periods of time, so no harm there! -- the RTP is a great placeholder tool for a jam, or honestly, even for a whole game. Your mechanics and narrative can carry a game far further than the graphics style. With the dev's note, if you want to include the info in the future, consider adding it after the game's resolution instead. But, definitely let the game speak for itself, rather than letting the RTP bring you down! :)
That being said, I did power through the game, and I think you have a really solid foundation to build something bigger and better out of. It's very text-heavy, which isn't a bad thing necessarily, but definitely consider if you want to stick with that style (and thus, continue developing with more of a visual novel style), or if you want to pare down some of the language parts (which aren't bad by any means) in favor of a little more action and visual effects to get the same information across. I can see this translating well to either experience, but not so much the combination of the two like what's going on currently.
I am glad that I opted to ignore the first impression and give this game a chance, but I wanted to make sure I mentioned that because you don't want to chase players away before they even get a chance to see the cool parts! :D
