Thanks for responding so quickly! I'd love to elaborate.
I'm enjoying the deckbuilding update, especially some of the new art, but have found myself occasionally missing the older releases which had fewer moving parts. Putting together a deck with pieces that synergize with your perks is a fun development of the formula, but the older 'doors' system was something I found fun in its own right. It offered an extra layer of risk and reward to the shop phase that's not present in the same form currently. ('Should I play a higher door now, or spend the money on more perks? Is paying for this door worth the risk that I flip the wrong cards and lose money? How much does my build actually benefit from the 'better' set of cards?)
The deckbuilding update also definitely raises the skill ceiling quite a bit with the added layer of complexity. In general, I think that's a good thing, but I also enjoyed the simplicity of perks being the sole 'moving part' of a build. I had a lot of fun experimenting with different perk setups to see how big of a number I could make, and the stable aspect of doors having fixed sets of cards behind them was certainly a part of that.
Also, I agree with what some other people have said about the warmer lighting, wooden desk, and other environmental changes making the game feel a little less scary. It's not a huge deal, and I think the new card art mostly makes up for it, but it does feel like a little bit of a downgrade atmosphere-wise.
In summary, while I don't dislike the direction the game is moving in, I find myself missing some of the simpler aspects of older versions. A certain part of this is probably just because of fond memories of initially discovering and experimenting with the game when it had just released though, and having access to the older builds should be enough to satisfy that. If I find myself playing one version a lot more than the other, I'll be sure to let you know.
At risk of making this reply absurdly long, I'd like to express how nice of a feeling it is for a developer to communicate so directly with fans. I appreciate it, keep up the good work.
