Thanks so much for checking it out and taking the time to give some feedback!
Some responses:
1) Were you running windowed at the resolution of your monitor and seeing the game be wider than it should have been? What resolution?
2) Thanks for the report, will take a look.
3) Awesome to hear! Since you've beaten the troll I hope you'll move at least to the next area, I think the presentation takes a pretty big step up there personally. The moving foliage isn't a animated or a shader, it's a rendering trick where the vertices of the sprites are pulled when an object is in contact with them.
4) This is actually a... feature. Some enemies have the ability to leap long distances to the player to engage in combat and when they do so they ignore level geometry. But It definitely presents as a bug a lot of time (I didn't say it was a GOOD feature) so I'll need to revisit this and either make it more polished or remove it.
5) Again, awesome to hear!
6) Understandable, especially since stamina is so low to start! Character leveling and attributes is a fairly new addition and I need to think more about how that curve will work. Consider that "in progress"
7) Good suggestion!
