I got up to the Thunder Boss before I stopped playing because I was tired of losing and I didn't feel like throwing myself at the battle over and over until RNG worked in my favor. The fight shouldn't have been hard at all, but the boss and 2 mooks kept using Storm and other magic dealing ~260-320 damage (yes the mooks were dealing the same damage as the boss) and I just died before I even had a chance to retaliate. Basically for every 1 turn of mine I got hit 3-4 times for a few hundred each hit.
From what I played though, the game was fine. There's nothing truly bad about it, it's just a pretty decent and average game. For what it's worth, I enjoyed what I played and that is what we're really after. The character portraits are pretty charming and I like the whole tower climbing thing to find Jason. The puzzles were simple but enjoyable. The combat was pretty simple, but I had fun nonetheless with it. The storyline was fine. I didn't get much of it (nor did I see the end so I can't say for certain) but it's got potential with what happens next. It's enough to get you interested in learning more, so that's good.
While the combat was simple, it was also very easy. I mean that as, the first two areas of the game are a water place, and fire place, and Lucy has a thunder spell and water spell. So pretty early on you realize all you need to do in area 1 is just use Thunder. It's fine, it's not terrible, but it's not the most engaging combat. All you need to do is use Thunder (and freeze/downpour for area 2) for each battle and you win. No thought required. Lucy has a bunch of spells of different elements, it would have been nice to see her use them more freely. Maybe that happens later but in the start it just one thing.
Overall it's a fine game, and we all know how much work goes into making a game jam game something fun and enjoyable in that time. I think with some more work (and time lol) it has potential to be better! Good job on the game! :)
