ONly 2 stars, but I see this is just a demo, and the game has potential.
- you should definitely give more time before the first crates appears when you start. I die 3 times on 5 hitting the first crates.. -_-
- the stickman should not keep running when is in middle air
- crates arrive slower than the clouds and this feels very weird..
- use bigger coins icons, maybe different sizes or colors or something else to avoid writing the value
- you need more kinds of obstacle or traps
and what about the multiplayer mode? are you planning to make a multiplayer version of it? this might be very cool, especially if you accomplish and amplify the items customization part. ;)
p.s. I have a stickmangames portal. if you make an improved version with multiplayer and a nice amount of items, I would definitely consider to sponsor it (but we'll have to negotiate before you post it here). let keep in touch! ^_^
