Alright, it's time to bump this because a LOT of updates have been made since the last post. I've added the following to the game, several of which address the above poster:
-The control scheme has been greatly simplified - one key now controls dialogue, selection, and attacking. Additionally, key mapping has been implemented, as well as volume sliders for the game's music and sound effects. I have also included a dialogue speed slider and a partially-implemented colorblind setting.
-I have finished composing the game's title theme, and it has been included in this build. Stick around to the end, and watch the title screen change alongside it.
-Attack animations have been greatly improved.
-Numerous other animation and sprite fixes.
-Small changes to enemies and combat addressing some complaints from earlier. More to follow in future updates.
-The inventory now adjusts so that there are no empty spaces whenever an item is consumed/sold/destroyed. I haven't implemented manual sorting since this is not a widely requested feature, but if it's something a lot of people want I'll put it in.
-Various bug fixes, including the ones mentioned in this thread.
-Lots of additional dialogues appear after level 1-6.
-Substantial internal refactoring - not visible to the player, but it makes adding more content to the game a lot easier in the future.

This is just what I can remember. This is all included in the newly uploaded v0.030 Alpha build, which can be downloaded here: https://bynary-fission.itch.io/battle-tower-royale
