Cool vibe! I felt like I was doing something wrong, though, because I couldn't get past the first "boss." It took me a while to understand that I had to use "space" to attack enemies. And I tried using "E" to interact with things, but I couldn't find anything to interact with.
Could you potentially add some hints to your game page? It also seemed like there was going to be some sort of mask I could use, perhaps after the first boss, but I gave up after a several tries.
