Thank you so much! We do plan to continue the project, and were on the verge of having five levels instead of one when the deadline got close. We plan on releasing a more polished version after the jam with all the ideas we had initially.
In terms of making the mechanics more complex, the initial plan was to allow the player to customize their dice, and the encounters were meant to support different dice builds. For example for one fight you might need a more offensive build, and for the other you might need to give your dice more "Defend" faces.
In terms of uploading to mobile, if it's possible to do so with Godot and we continue the game to a point we are proud enough in we could potentially attempt to upload it to mobile.
TL;DR: Thanks a lot for the kind response! We are in fact continuing the game and making the gameplay more in depth and more balanced :D
