First of all thank you for playing Digi Card Prism Vikings. I am glad it did make you laugh a lot. I am aware of the encounter rate being extra high this was to counter something the game was doing in the last couple hours. I am adjusting it for version 1.2 as well as all the other glitches and such that I can fix that is listed in the dev log video. As for Fred and Titania's attack buttons not appearing I am aware of that and it's a problem with the plug in and RPG Maker MV and could happen to a couple others but they are the most likely ones and usually only happens on the first turn. The plug in maker did discontinue it as he's writing a new one. Unless, we find a better one the team likes more then we will switch to it.
Funny thing one of the testers did the opposite letting Kvasir do so much magic damage and I was able to agile & power the game with Titania. It’s a result of the card system we are still working on revamping and fixing and tinkering with as it’s still in concept and if we get a full version we will be finessing more. As for the switch puzzle I can tell you the information was provided in room and in the bio for Aesir. As well as any knowledge of Norse mythology could help with. I am thinking on changing that puzzle as it's one of the last parts and I was on the time crunch when that happened. The huge house problem was a counter to the first game I made where the houses were "too small" according to comments I got. Plus Titania is supposed to have a large house for 5 people and having a father that is a doctor (sadly this dialogue didn't get in 1.1 but will be in next version). I didn't get all the assets in I wanted so it seems larger than it should have been. Also we double checked and the only part that really had the pass through was again Titania's house though I'm also trying to poke holes looking for other gaps and entrances we missed.
Thank you for your comments and hopefully this will help make a more pleasing version soon.
