I'm a bit late.. but I started playing Forgive Me Father 2 after finishing the first game in the past few days. It's both an improvement and a downgrade compared to the first. The sequel has MUCH better level design. The guns also feel much better to use, even if there isn't as much variety yet. Both of these things have made it so that I would rather play the sequel even though it's got far less content as of now.
Now for the downgrades. You can only play as one character, when there were 2 in the original. There's also currently no voice acting which is a bummer, but it will be added eventually. Each character in the original game had different abilities and voice acting, but some people didn't like the journalists voice overs so this might come down to preference. The gun and skill upgrade system in the original was more complex and branched out. I also like how you were given plenty of reset points for completing levels, so if you regretted anything you bought you could reset and experiment with different builds. In the sequel, you just buy stuff from a shop with 2 different currencies, and as far as I can see there is no way to refund (but I'm not entirely sure on this). The abilities are also lacking in variety in the sequel and aren't as enjoyable to use, though I think some of the abilities in the original were kinda useless and bloated.
The game will continue to be in early access until the end of this year at the earliest so they could make substantial changes, and I haven't read what their plans are for future updates. I think I've nearly finished what's available in the current EA build of the game, but I have enjoyed what I've played and expect the full version to be greatly expanded on since the original had far more content. If it was one of the reasons you plan to buy the shooter bundle then I say go for it, just don't expect there to be much content for a while
