do this with slightly better graphics (keep the stick men but fix backwards swimming fish, turn glass from blue plastic to glass, etc) and make it multiplayer. Possible make the upgrades less repetitive and practical (instead of wood, cement, glass, gold, then the product gets a bit better, wood, cement, glass, gold. When I say practical I mean like having a glass staircase). Man I tend to spam games (not on purpose though).
Sure I'll take a glass staircase. ONE DAY LATER "we now gather to mourn for Meyershark who died at age LVL 546 from slipping on his impractical stairs and killing himself in the terrible process".
