Game freezes when the first upgrade is obtained without indication that something is being put into the dice slots. A highlight on the dice slots will be better.
HP dropping to 0 don’t have consequences, which essentially means currently the player is invulnerable; but judging by the speed it’s dropping to 0, if it is implemented the game probably won’t be able to progress through first wave. Try rebalance the player HP amount, the enemy attack strength, and the enemy speed to at least be able to pass first wave without depleting HP in a casual play.
The core “roll of the dice” concept is only used as a random effect, which isn’t really nice to control what we want to use. Maybe expand on this a bit, explore how the player can “use” the dice they rolled, not just apply the effect once upon rolling.
Overall a nice try, but needs more polishing on the implementation.
