I like it a lot—the vibe, the characters, the art, and the writing.
While outside of combat, I think it's better for the team members to not have collision, or there will be awkward blocking in narrow spaces.
The bugs seem bugged. They can attack, but don't actually hit anything.
Not sure if after killing the big bug and reaching the stair it's the end? I got back to the title screen after hitting the stair.
That's all the complaints for now. Nice work, mate.
