I like the pixel art. The tutorial was nice, albeit long and faded out the screen whenever I restarted the level. And I couldn't skip it.
The controls were good, but there were lots of collision issues that made it hard to navigate.
I wasn't able to pass the first level. I tried stepping on the red button, but that didn't do anything. Reaching the door itself didn't change the level either. I even blew up the bomb with the fire on the chain (which was cool btw), and it really just opened up the path to the door. I wasn't sure if there's more to the game.
