Update 4
It's been a week since the game launched, and fortunately, there haven't been any game-breaking bugs. A lot of people enjoyed the game, and we're really grateful for the community's support. I've gathered plenty of feedback, watched live streams, and collected as much information as possible to improve the game. I'm happy to report that I've fixed all reported bugs and those I identified during testing.
Boxes
Fixed a bug where the box would shake when the camera moved, affecting some double levels.
Fixed a bug where the box would hit the wall on a jump-thru platform, and the box would pass through the platform.
Adjusted it so that the box only makes a falling sound when the fall is greater than 4 pixels, avoiding sound in some places where it shouldn't occur.
When the box is jumping on the trampoline, the sound is only played if the box is visible on the screen, affecting double levels.
Ice Character
Fixed a bug where it was possible to kick the ice block after pressing the button.
Improved wall and object detection to prevent the ice block from entering walls.
It's no longer possible to create ice very close to the fire character, preventing accidental deaths.
Fixed an issue where the ice was not created if the ice character was backed against a wall.
Fire Character
Fixed a bug that caused the fire character to freeze if it is blowing fire animation and is kicked by the ice character.
Fixed a bug where the fire character performed a double jump when climbing the ladder.
System
Fixed a bug of the analog stick pointing down in the menu, which would scroll to the last option.
Fixed the analog stick bug on the level selection screen; now it works normally.
Fixed the error that prevented the game from running on Linux in Steam compatibility mode.
For testing, I used the VMware virtualization tool with Ubuntu, as you can see in the screenshot; it's working now.
Thanks to everyone for the tremendous support. If you come across any other bugs, please let us know, and we will correct them as soon as possible.
