Thank you for the feedback! I’m glad you enjoyed the movement and the laser gun! I’m the same way when it comes to instructions or tutorials, so I designed it to gently nudge players into doing things as intended, while keeping it as brief as possible.
The suggestion for a brief invulnerability window after being hit is an excellent idea, and I think it could work really well with the undo mechanic too. Getting pushed through walls sounds like a fun (though unintended) discovery, thank you for pointing that out!
Cheers for playing and for your thoughtful suggestions!
