We are making some good progress. We started to add more content to the game which will be unlockable with the special currency which can be aquired by killing a stage boss.  

In the starting lobby you will find a special room, where you can see all weapons etc. and unlock them. The unlocked weapons etc. can then be found in the next playthrough.  

We are experimenting with some abilities for melee weapons. We want to buff melee weapons with an active skill.  

We plan to implement around 100 passive upgrades and around 40 different items, weapons and shields for the release.
