I never played the original game when I was a kid but after beating this remake I wish I did. I would have loved this game back then. The levels are challenging and finding all of the collectables and progressing your character is a blast. The music and artwork are fantastic and the fact that you can swap between the 8-bit and modern styles on the fly is really cool. You can tell that a lot of love went into making this. The only sort of bad thing that I can say is that there are a bunch of enemies that are really annoying to deal with at first but even then, you just need to learn how to use the tools that the game gives to overcome them.
I played through the entire campaign and loved it. You can tell that a ton of effort was done by the devs. The weapons are cool, not as outrageous as Duke 3D but still fun and each feels like a tool that's best used for specific enemies and situations. The enemies are pretty interesting too, not super smart but they still give you a challenge. Each level is large, well made, and filled with secrets that are fun to try and find. I say ignore all of the drama and enjoy an awesome game. As for the drama, I think it's dumb. A few of the devs (who are entitled to their opinion), expressed their opinion on a controversial topic on the Discord server they were using to promote the game. Not sure why they thought that was a good idea being as at that point, you are acting as a representative for your company and probably should have done that somewhere else. The internet did what the internet does and people complained. Then some guy used noclip and found some language that is offensive to a specific demographic. Voidpoint and 3D Realms did what businesses do and tried doing damage control by apologizing and said that they will take out the offensive language. Thing is, they've said that they are only taking out the thing that you need the noclip cheat to find and changing 1 joke around. Nothing else is changing. But people are now review bombing the game on Steam and GOG because they say the Devs and 3D Realms caved to ResetEra (the forum that complained) and are censoring the game. Trust me, the game is still loaded with politically incorrect jokes, if that's all that's changing, who cares? I think both sides of the argument are overblown. If you like old school shooters, give this one a try. Sounds like it's still going to be the same game even after they patch it.
