1. Yes, I could find and complete both endings (at least i think so), but only with a friend's help. It took us a while to figure out how to get the shovel or what to do when talking with Syrios.
2. I was entertained by all the combination dialogues so far, so no complaints there.
3. Iggs wasn't really helpful, he only provided funny commentary. It might be beneficial to change the dialogue slightly so he can give better hints as to what you're supposed to do.
My only other complaint would be that the game would freeze every few minutes, and was lagging a bunch afterwards.
All in all its a really interesting and funny game, 11/10 from both my friend and I. We can't wait for the full version, so please keep up the good work.
