Viability: The game is playable from beginning to end, tho during the part where your HP is draining it would be better if that draining was displayed for all of those passages. i thought i was safe when i got off the passage that it was displayed on
Presentation: YOOO IT LOOKS SO COOL
Theme: there's definitely a clear theme of being a lil guy trying to escape from a techy facility. i think it's pretty cool to mix the analog tech designs with the futuristic ideas of superpowers/genetic experiments
Engagement: whale!!! it really sparks your imagination, especially at the end but no spoilers :)
