it is great, have a potential aspect to expand the game, and i'm not sure are you planning to put a skill tree. I mean the arrow mini game is very good concept to help as starter game, u can upgrade which aspect to focus on the character instead of skill tree that need to get the previous upgrade before getting the one needed, (example : power I > Power II > Att.Spd I) something like that, to get the att.spd u need to upgrade the power first that's why the minigame is a good starting concept. If u still want to put skill tree, to me it is better if the skill tree only affecting the mini game instead of direct stat on character.
for the potential aspect to expand :
- Different Map (Maybe u already have the idea and if u already have backstory it could help expand the story)
- Challange mode (instead of just increase difficulties, it give debuff or terrain change like floor is lava or something )
- Special stage (maybe you already have some idea, but currently still lacking to me (gold rush, cemetery(soul harvest event)))
- ritual lock upgrade (upgrade that can only be obtain through ritual and the soul needed increasing each ritual, so the ritual not just give gold or starting weapon choices)
for the issue that I feel its annoyed me:
case : I dont have enough gold to reroll and the option I got are useless.
the option I got are all upgrade for additional skill (extra projectile of ...; extend size of ...; damage for ...;) while i dont have the skill effect.
like I don't have the chance to launch missile but i got the upgrade for extra porjectile.
hope u fix it, so if u dont have the skill u dont get the upgrade for it, u dont have chance to launch missile then u dont get any upgrade for missile something like that
Sorry if its to much, but I rlly like this game, and that's for now maybe I got some idea I will put it in bellow this
