I tried to look a little more into Helltaker because I was curious about something.
Did the game get covered by any news outlet?
From what I checked it did not get covered by any big name one in the west and it didn't get covered by any smaller one either.
I checked IGN,Kotaku,Gamespot (Gamespot does technically has some information about the game but it looks like it was pulled form a database but doesn't have any articles about the game),Eurogamer,Polygon,RPS,PCGamer but non of them seemed to have any information about the game. PS I only checked the English Eurogame and English IGN and not all of the European ones (which I probably should have done seeing how the game in question is from EU, Poland)
I even checked some other places like Gematsu,Nichegamer,Siliconera and they also didn't mention the game
I even checked on this one Japanese site that I go to from time to time and I know that they regularly mention indie games, even they didn't seem to mention the game at all. They may end up covering it in a few days along side with an interview with the dev.
The only western site that seems to have covered the game is some place called GamersHeros and they are also the only one with a MC score for the game.
I think I can see as to why it was not covered though, when I was checked the Japanese site that I normally use I noticed that there was a lot of articles around May 10-12, so those must have just been very busy days and now that I think about it, I don't think I realized that Helltaker released that long ago, I thought it just released in the last couple of days. but it's roughly been 2 weeks at this point
I also checked on Era and it would seem that there is only one post, one made by
Jawmuncher which is likely why they asked if it was mentioned here since there has not been much talk about it? and even that Era post in of itself did not seem to get that much attention to begin with.
So what to know what big name publication actually ended up covering the game??? That's right Famitsu!!!!!!!!
Here is the article in question
2020年5月11日にSteamにてリリースされた『Helltaker(ヘルテイカー)』のプレイレビューを掲載。プレイはサクッと、だけど濃密。しかもこれ、なんと無料!

And even then it would seem that they only covered the game recently since it seemed like they saw some Fan art on Twitter in the last few days. There has been a decent amount of art by the way, I guess that after doing that Sailormoon redraw thing people wanted to do something new.
The game now having a Japanese fan translation and being very low spec and also being able to run on Mac likely helped to get some of these artist to also try the game (and it has a small install size as well). The system requirements for the game are just 300MB!!!!! (that is it, it doesn't mention anything else) and it's free. So even people like that one composer of Streets of Rage can play this game on his crummy PC. Also Swery65 can play this game on his new PC!!!
By the way on Steam the top rated screenshots seem to be from Japanese players. There is no native Japanese support for the game but the dev did make a video letting people know how they can fan translate the game and it would seem that is what ended up happening.
lashman IGN Japan covered that one Riot game, the one that you were looking forward to and that already released.
By the way within 2 days the game already had 500 reviews and I guess that within a week it had reach overwhelmingly positive reviews.
So what did we learn? Fan art can help give your game a second wind.
I would look into this a lot more but I already spent a decent amount of time just looking at this information.
