Nice art (especially in the menu)!
The roguelike elements were pretty cool and the main mechanic was easy to understand. Also good job, for providing in game descriptions for items. One issue I have with the main mechanic is that it feels random in a bad way - you either roll low number and don't get many energy, or roll high and can do more actions. Ideally you want all player dice to feel usefull no matter what he rolls, by providing some different options for dice utilization (for a example attack could scale with dice value, but the shield uses any dice and provides 3 armor). Still the game is great, and I enjoyed it nonetheless. Good job!
