This has become my go-to game during my work lunch break. I think the gameplay concept is awesome. The frantic chucking of dice onto the board to stop an enemy who just wiped out my front liners is one of my favorite parts. I also enjoy the whole dice management aspect after you reach the max. Its all bout trading off your worst dice till you get a decent main set.
I know this was a short game-jam creation, but I think it could be fleshed out to be an even more amazing game with added locations/visuals, new enemy types(or alternate versions of current ones, i.e a Red Armored Knight with double health or fast Babies) that appear over time, and different modes. Maybe a quest mode that takes you to new grid layouts each 20 waves, like you are moving towards the castle or kingdom that started the fight and take them on at wave 100. Alternatively a dice lock mode where you have to use the dice the game gives you to survive, no choosing.
All in all, this is addicting as hell and I love it for making my downtime more enjoyable. It's just that the set 4-5 enemies that only keep increasing makes it a bit too easy after wave 15. By that time I have a full roster of those heavy hitter skellies and a cannon armada behind them. Once the initial panic toss is over, I've got the full defense set up in about 30 seconds. Nothing gets through.
