This game is so ambitious for a 48 hour jam, congrats on pulling it off!!! Also, despite lack of audio, your game has one of the best art styles I've seen so far :) Played it right to the 'thanks for playing' screen. There were some bugs when the enemies attack, it seemed that the tank took way too much damage at some points (thankfully I got some nice heals rolls!).
The dice-lock mechanic was something we also wanted to add to our game, sadly we didn't have enough time to make it work. Congratulations on an excelent submission to the jam, if this is what you do in just 48 hours I'd love to see what you do with more time.
