So there is a way to skip it, but that really should be made clear from the get-go. A lot of games have a large "press --- to skip" on the intro screen.
Aside from what's already been mentioned, I feel like that intro goes on for WAY too long since there is no way to skip it. The text passes by painfully slow, and since the music loops after only about 30 seconds, makes that very noticeable as well-- most of the OST seems to be a few notes progressing upward and then repeating.
As for combat, I feel like it would move along a lot smoother if you could select your creature's attacks all at once rather than: select, attack, select, attack, take damage, take damage. I also feel like gameplay-wise, this is nothing too new and that I could go play Starbound and tame monsters, or play Pokemon and have a similar experience.
Also the AI is isn't very smart in any situation. With that first boss with all slimes, my damage got killed off and I had one that was weak to water, and I still won because they would attack my slime even though it resisted them. Or they'll attack the creature that has a massive shield. Basically, there's no feeling of challenge at all since bosses don't use any strategy, they just have X buff that makes them a little stronger. I mean, what's the point of weaknesses if only the player is the one actually using them? It would be no different if the abilities were just a bunch of random slashing and buffing attacks.
Heck, the parkour feels more difficult than the gameplay at times.
I really like the idea, but there are games that have been presented much better than the way it was here.
