Great game with a really fascinating idea.
Game Design:
Game is interesting in terms of design, but I just wish there were some checkpoints or so, as game was too punishing imo.
Fun:
I had plenty of time, especially because of great game idea. I had a problem with alien tho. I felt like he is unkillable (maybe that was on purpose) and so I didn't get any further.
Innovation:
That's innovative for sure. Idea can be really well developed if you want to continue working on it!
Theme:
Also a great approach to the theme. You have to really thing on how to use it and just hope that level design would require player to change more.
Graphics:
Enjoyed them :) Animations are clean, alien fight is also entertaining. Good job on that
Audio:
Nice music, well fitted into the game. Sounds are also quite good.
Overall, I did really enjoy playing it. Hope you work on it in the future.
