Well, I think this is easily the best game I ever played on itch.io!
I especially like the rogue-like permadeath, but I see three problems related to the "death drops":
- They are too random: In my last game I only got "new dice" and "remove dice" in the first 10ish waves and only "upgrade dice" and "heal hp" in the last 10ish waves. The other way around can also happen and is way more useful.
- In the first waves, the new dice you can get are boring. They are the same you already have. They should be at least one point better.
- The heavy dice are far better than most others, since they are the only way to have more than three dice on the board. In my last game I had three heavy dice and losing was out of the question henceforth.
Apart from that, moths (the healers) are extremely hard to beat and annoying in the beginning. I think they should only show up from wave three or so...
