New build is here.
This one introduces one very important change. A feature called "reactor". You will no longer be able to play endlessly. Although for a while it is possible to extend the playtime. Current balance is completely off. From starting 20 minutes in three levels (after 14 minutes) I was at 37 minutes left. The thing works by buying additional time for energy. You get more energy from enemies now, but with every minute passing, the cost for additional second is growing.
There is a new device, a terminal that you can connect to. It is at the stations between levels. You should go to "energy transfer" to move energy between devices or buy/sell time.
Another thing is a new zone variation. Bridge with cannons. It is a platform crossing (between towers over a chasm) but instead of enemies dropping from the sky, there are just a few cannons (huge turrets) on the other side tracking you. On each platform there are mid-sized railings that you can hide behind. There are no "transparent" railings, so if you crouch/duck, you're almost always fine. Unless there is a very steep angle. On challenge, without navigation, it is currently the most demanding level. Completely different in feel.
To try new zones, there is a new option added when you start a game. Select "only new" to check new zones. Well, one new zone in this case.
I am quite happy with the reactor feature as it opens a lot of possibilites. It just requires balancing. I will be changing that in coming updates.
There will be also a post dedicated to reactor feature. Reasons behind it and things that it makes available.
