Next small update should mostly focus on balancing the gameplay rather than adding more content meaning i will try to balance the prices better so gameplay is fast enough and fix the time it takes to obtain rebirths.
Sorry about the inconvenience.
Less income for less cooldown.
Basically trading something for an upgrade.
Yeah as of now the game only has a few cooldown upgrades and each decreases the cooldown by a very small amount (mostly unnoticable). Next update should make the demo slightly more easier (with that making the cooldown changes noticable) and adding more upgrades to the full version.
If you were using the browser version its because games run slower there, due to that the content is very small.
(i probably should include this information)
