Hello! I was planning to release this bug fix for the shop upgrades in the weekly update but since the update is quite big I had to postpone it for this Friday.
I will look into the cloud sync because it should work! Thank for reporting that
The tier bonus calculation is a flat multiplier, 50% extra per tier level.
The upgrade you mention does the following: when you craft and item. It has a chance of triggering an extra instant craft. You still use the materials but it's done instantly.
I want to have a solid base before adding content, so I'm spending a lot of time making the current systems more enjoyable. For this Friday I will have an update for the forge so that it's a 2D environment with interactable elements to make crafts go much faster while playing actively.
Also if you don't mind me asking, how did you find the aiming controls for the abilities on mobile? Where they easy to use? Also, what would you say is the best element the game has?
Thank you so much for leaving this comment by the way. It really helps.
