Yes the TNT thing is on me, I forgot about it and couldnt update the playtest later on since we had bunch of new stuff that needed deeper testing, but thank you for pointing it out!
Well, this build is still missing some of the collectable models, and those values need to be higher to trigger for sure, really sorry about that, we do much better in terms of balancing now. I hope it wasnt too frustrating, but this playtest helped us a lot to point out many things.
Thank you so much for giving it a chance, we wish to see you in our next update!
