If you get hit while having your jump charged, the being charged sound effect stays active even as Chip. Other than that, I had the teleport-one-room-below bug, when I was two rooms above the starting room.
I like the bomber, although I feel like it was probably a recent addition because it was only used in one, possibly two instances and didn't really feel fleshed out yet. Glad you managed to come up with a good way to encourage switching between Cannister und Chip though. Pretty good additions, looking forward to the date.
