I'm glad you enjoyed it.
The distance is short because you only roll the distance of the dice. If it says 1 on your head, you roll 1 square.
You reload by Rolling over enemies and you have 3 bullets. If you're out of bullets, you can't shoot until you roll over someone.
Making kiting difficult was part of the idea. I understand its frustrating but I didn't want this to just be another top down shorter, where you look like a dice. That wouldn't have been very creative in my opinion.
I hope you still enjoyed it and let me know if there are any ways i can describe the idea better! Thanks for playing
