Nice idea, great visuals! However, I think that way too much is happening on the screen at the same time. I was able to make it to the end of last wave, but lost right near the end. The biggest problem for me probably was the vulnerability of dice - they die almost immediately when surrounded by enemies, which they need to be constantly if they are to deal damage. It takes them too long to land, to start moving again and to get back to the tower. Sometimes they are completely stunlocked when the enemies are near your base. If you really want to keep their health as a mechanic, I'd suggest raising it, polishing their landing, movement and adding (more) invincible frames on getting hit and respawning. Still, great game, love the amount of stuff I need to think about in a TD game!
