We played it at the showoff at the physical location. We had a few criticisms and I can relay you to them, they were this:
The game was a bit unclear in general. We weren't sure what we were supposed to be doing or what exactly we were doing until we played it a few times to figure out how it actually works.
The game didn't have a lot to engage the player. We played quite a bit of it after we started understanding but we all quickly fell off when we realized it was only the one small game, though it's okay for the two hours you said you'd do it in.
Additionally, the game was a bit too difficult. We struggled with actually understanding how the game worked partially because we'd die before we could understand what was going on. I believe the game is also a bit too difficult in general as it can seem a bit unfair.
However, I will say that for two hours, the game was pretty cool! It worked and it had a purpose. I applaud that!
If you want some additional critique, I can return to it for a little.
