Pretty promising, if basic, game.
Fairly easy to cheese by jumping on the chest then intermittently coming back and purchasing upgrades.
Sprites are pretty nice, music and sound work well. Didn't find any bugs.
I'm assuming from your profile this is your first game. If that's the case you did quite well.
Good game, and even better developers.
Always giving out freebies, updating regularly, and generally nice people!
More than happy to support this product.
IDrakonI: The text says "Build in steps of *1 or *10 or *100", not "Build *1 or *10 or *100" The cost is consistent as well. If you have 5 assembly modules, and pay for build to next 10 steps, it will only charge you for 5, not 10.
I did that so you had an extra warning as to when your time is up, I thought the numbers in the background weren't always enough.
