This is still one of my favorite games on Kongregate. The lives system ensures that you actually take in your surroundings and solve the puzzle; otherwise there'd be nothing to stop you from just brute-forcing the solution.
This game is okay, but it really misses the mark on what makes games like Sky Island and FEZ the interesting brain-twisters that they are. In those games, the forced 2D perspective allows you to physically bring together platforms and traverse obstacles in ways that you simply couldn't with a standard 3D perspective. But in this game, you are traversing a normal 3D world in normal ways, and the forced 2D perspective just makes it difficult to find your way; not nearly as engaging.
So to melt the ice, your proposed solution is not to simply wait for the ice to melt in due time, not to melt it with your own body heat, not to crack the ice with a hammer, not to set it on the windowsill to let the sun melt it... but to SMASH OPEN A HOLE IN THE WALL TO MELT IT IN THE SUNLIGHT.
Level 105, and I still haven't unlocked the final game despite throwing all my credit cards at the Gameplay Lootbox. If I assume that there is a 1-in-12 chance of getting any given gameplay for every level I earn, the chances of never unlocking a single game after 105 levels is less than 0.0002%. Clearly there is some behind-the-scenes rigging going on here.
The price for the next upgrade is pushed out of visible range when the speed gets to 10 or higher. Also, the only way to change how much you buy per click is to go into the options menu.
The font size will be fixed in the next update. And in the options menu, you are allowed to buy +1 speed, (up to) + 10, or All. (As many as you can buy at that time.)
Also, the original Minesweeper allowed you to place flags just by right-clicking. Considering that this is programmed in Unity, and right-click functionality is available to players, there's no reason to have to toggle a button in the upper-right every time I want to switch between revealing and flagging. This game is a downgrade in all the ways that matter, and an upgrade in all the ornamental fluff.
First move I made on the board, I landed on a mine. That's not acceptable; even the original Minesweeper knew to only generate mine positions AFTER the first click.
In the subroutine that spawns mines, make the following check: "If (new mine X-position != player X-position AND new mine Y-position != player Y-position)", and only if that check is satisfied should the new mine be placed.
