I really love the reveal of the second half of the game, it got a laugh out of me lol
This is a really great "meta-game". I found both parts of the game pretty enjoyable, and I had a ton of fun switching between the two.
On the last expansion, I sometimes ended up with nothing but the background showing up if i pressed the attack button and died at the same time, nothing else seemed to show up (the player, enemies, foreground). This gets fixed if you die by holding right though, so i guess it's fine.
I found this one really cool. Keep making awesome stuff!
