Thanks for playing, I appreciate your feedback!
Having a tutorial for the playtest makes sense, there's one for the full game but it got disabled due to the jump-to-fourth-level thing I did.. perhaps I can enable the tutorial for the playtest and have it jump to the fourth level after.
Regarding the dinosaur auras and mushrooms, this is very valuable feedback. I've noticed others also having the same issue, so that's a great indication that the gameplay needs to be updated and/or more hints need to be given. I'll be making some changes soon about that.
Thanks again for playing!
