Have to say, as far as wanting to have ALL the extra turns awarded for the multiple cascades after the initial one… I don’t think that would be that wise. Hell, one game could literally last many hours! I personally think it’s fine as is, or if anything maybe throw in additional maps 7+ cascades, or other items such as Gems, Keys, etc.
I usually do well as it’s setup now, and can average 3-4K a game, and sometimes get a nice bounty at the end. The last TH game I played last night, I had 3 vaults, and I believe around a dozen red/green chest. Ended up getting 2 keys also, one of each.
Lastly, I do agree with the end screen disappearing way too fast! Not sure why it couldn’t be set up like everything else and just have a continue button? Just makes sense, and not sure why the auto closing is needed? Would help one to see what all they achieved, without having to try to snap a screenshot, which I’ve heard a lot of people here mention. … Just some thoughts.
