I just finished playing the updated version of the game. With just a few changes it felt so much better. Those little sound effects added a lot. No more falling for eternity down endless pits. No more sticking to the sides of blocks. No more falling halfway through the floor during the boss fight. The level design looked nicer too. I still saw a few errors in the debugger:
ERROR: Node not found: raycast-x
At: scene\main\node.cpp:1520
ERROR: Node not found: raycast+x
At: scene\main\node.cpp:1520
ERROR: Node not found: 1
At: scene\main\node.cpp:1520
ERROR: Node not found: 2
At: scene\main\node.cpp:1520
The errors didn't affect the ability to play the game though, so it was no problem for me. You guys did a good job improving the game in a short amount of time. Keep it up!
