Viability: Simple but addicting (I want to get all the coins). The elements are working well together. There may be some spots I had a hard time jumping on the platforms but it was rare.
Presentation: I like the little character that follows you around. The map is well thought out and I am excited to see what the art would look like.
Theme: I am not sure what the theme is but I remember you said it would be alien-like. So I picture like cute little alien creatures.
Engagement: I played this game for to long! I was determined to get all the coins. (I don't think I did though)
