Hey snof, great to hear that feedback from you, thank you! :)
The Teleport/Block issue will definitely be fixed in the upcoming version. Regarding the balancing, it's really helpful to get that kind of feedback. With the data from the Technical Test, we hope to get a better understanding of the balance and adjust things accordingly.
In general, it would also be great to get some additional feedback via the survey. This helps us a lot with the further development of the game. And we're always open to cool ideas... ;)
