The game is really cool, great idea. I found a litter hard to get the controls first time even with the tutorial. Some stuff was kinda strange and appear to not be working. In console window showed up this error:
ERROR: emit_signal: Error calling method from signal 'input_event': 'KinematicBody2D(dumb.gd)::_on_dumb_input_event': Method not found.
At: core/object.cpp:1238
Other than that the art and music was very good.
If you could play my game and give some feedback I would be really gratefull.
