That means a lot, I'm glad you liked it. I admit it takes some time to complete the game based on how you invest the resources, but if you give it a visit again, make sure to keep a stack of bullets with you the first two runs and after that, invest in the gun upgrades. You'll be able to complete in just a couple runs. The smallest amount of runs I've managed to reach the other end in so far has been 5 runs.
Anyways, thanks a lot for the feedback and I sure hope you revisit the game some time and manage to finish it :)
