This is the second time I play the demo because I wanted to find the character I skipped last time.
As always your art is really appealing and high quality, and I find some of your character designs really creative. In particular I like those fluffy bat snow things that show up near the end.
I didn't experience any major issues while playing although the player's sprite showing in front of a wall when pressing against it is a bit distracting since that happens a lot in the area with the giants and the secret hideout requires doing just that. I would also prefer if the tank was a little bit faster.
