Infortunately for me I ran into two critical bugs. The TAB touch don't work on my browser and release the mouse lock on from the game, which do not feed tab to the game and therefor prevent me from switching characters. So I can't go past the tutorial. Since I cannot reassign the touch, nor download the desktop version of the game I cannot play it.
Moreover, when I press space to jump, the dog is stuck in a infinite loop of jump and makes it really slow to walk, and cannot run anymore. So I cannot even jump above the crates to go past the tutorial neither.
Therefore i'll rate this game it by his old playable version on desktop before the tutorial released. It's a good use of the art, and the concept of switching character to suicide on the environment is great. This would deserve more polish to make it a full completed game. Thanks for your work !
