oh wow, i really like this pseudo-deck builder rpg system you have here! the contextualization of the orbs representing an element that can be used to cast its respective spell is very neat, with the orbs kinda reminding me of magic's the gatherings 5 mana types! also the way you just cast spells is really fun and engaging, rather than a simple button to click to cast a spell, i like how you actively have to drag the orb into the slot and then cast the spell after choosing a target, very nice! though due to both my orb rng and enemy encounters, i found myself to be using flare (the red orb) the most and either didn't get the others as often or wasn't put in a good position to use them or discover what they did (because of the 3 enemy encounter). still a very nice system with a good foundation, saw the pic down below the comments talking about combining orbs, and yeah that would be awesome to have if you continue this! also i do like the myst style movement (or maybe since this is a turn based rpg, etrian odyssey is a better comparison?) but i also do agree with some people that it is a tad too slow. if you still decide to stick with this movement system, yeah making faster would definitely help!
i also really like the vibes of the aesthetic! the mixture of 2d and 3d elements provide a neat contrast with each other, with the 3d elements being more of these desaturated darker colors making the brighter saturated colors of the 2d enemy sprites pop out more! also like how the enemies show up in the same world you're moving in instead of just loading a battle scene, very nice. the enemy designs all look pretty cool and the ui is also laid out really nicely! the animation and the presentation of the battles are also surprisingly polished and look really nice! also gotta compliment the audio design here while im at it, because the sounds while interfacing with the menus are really fun to listen to and left a pretty strong impression, very nice stuff! lastly the cutscenes were fun to go through, they provided a lot of nice context to tie the mood and atmosphere together, really cool stuff!
as a fan of rpgs, this was very pleasant to go through and seems to have a lot potential! hope you continue to work on it, great work!
