Nice game prrototype... clean, smoth, concise, clear ... but rather lacking in content and the scaling of the number leaves a little to be desired... too fast which reduces the players opportunities for interaction extremely quickly... there's a reason most of these games scale so quickly but it are not dull... their bonuses scale at an almost even amount and there is too great a difference in this game - primarily caused, I think, by the "Skill" scaling... collecting them is too slow compared to the rest of the resources, of course all this would likely change with more content so *shrug* work out a better balancing algorythm ;)
Keep up the good work :)
