Nice try.. But the shop is too expensive for how quickly bosses appear. Fix the prices, or lock out bosses till the upgrades are bought. Sadly, the sit and shoot at spawn mobs type game is so very passe.
Hills.. slows down trains - Train robbers.. employ guards - Random bonus buildings.. if you have the right freight(etc) driving past random building doubles payout at next station (so a miner hut doubles ore payout ) - Buy lighting for passengers ... more passengers will travel at night - lots more ideas if these are practical
wont save. horrible loading times. clicking backwards often resets game. quickly becomes boring/check in an hr to do things. needs lots of work on a decent idea.
Oh? I find it addicting. What do you think I can do to make it more addicting for you?
