Lots of potential, but far, far too overwhelming to the new player. You need to HIDE EVERYTHING at the start of the game and ONLY REVEAL AS NEEDED. A+ for effort and layout, Z- for new player experience.
Nice reimplementation, but please for the love of god, add an option to single click numbers to dig adjacent mines. On expert mode, 600 squares, 120 mines, say I double-click 300 squares, that's 720 clicks (300x2 + 120 mine clicks) per game in 10 mins. Your game gave me actual RSI pain in 20 mins (1440 clicks!). A single click option would reduce clicking required by 300 per expert game.
"The only building upgrade I can access is Tougher Storage, 30k love, 250 plank and 25 metal. I have more than enough of all of them, but it won't let me buy it. Unfortunately it looks like my game ends here." Looks like there was a number rounding bug. I had 25 metal, but couldn't buy the Tougher Storage upgrade till I had 26+ metal.
The only building upgrade I can access is Tougher Storage, 30k love, 250 plank and 5 metal. I have more than enough of all of them, but it won't let me buy it. Unfortunately it looks like my game ends here.
Also stuck. Curing shed is the only building that can store fish. Have level 24 curing shed, stores 5.2k fish. But upgrading it requires 5.42k fish. Impossible!
I finally did the 4 lamps puzzle in the lower right room. Probably the hardest one of all and many people are stuck on this. The secret is to start with the bottom two then the top two. You need to be able to jump from the elevator right onto the button then back onto the elevator, then jump onto next button, back onto elevator. At this point it will have moved up enough to let you jump right onto an upper button without waiting. There's plenty of time if you do it like this. Upvote to keep this solution visible please.
Seems to be a bug with MineBoost. I bought 5 levels of Mineboost, and my SFC/s afterwards was the same as before, as shown in the Mines command. Perhaps the Mines output isnt showing the MineBoost bonus?
As fr1ggy said, you'll want to approach the bottom right part of the puzzle a little differently ;) Best of luck to you! edit: vegetalss4 has some good advice too!
(2/2) The only issues I have are: (a) sometimes mouse clicks are missed when going round a corner -which affects later levels - but key presses are detected perfectly. No need to bug hunt, use your time for better things. (b) sometimes I wanted to repeat a level a few times to get 3 stars, but it is annoying to have to go through the home screen multiple times. The 'Home' button could be replaced by a 'Levels' button and the 'Home' button moved to the levels screen. Finally, please give us more, harder levels - your designs are lovely!
