Congrats on your submission! I love the artstyle and gameplay loop, it's simple yet very entertaining.
Here's my 2 feedbacks after testing it for 15-30 minutes :
1. The aiming system
There seems to be a slight offset when you shoot making it difficult to aim properly. If you used a raycast maybe adding an offset of height on the hit point could have helped. It entirely depends how you made the system work though. The arrows are very nice, seeing the juice particles at a distance is very rewarding ^^
2. Enemy status
Another small feedback would be the enemy health, we don't have a health bar or anything (which is completely fine) but having no feedback at all on the current health status can feel underwhelming. Maybe you could make it so depending on the health you show a different visual on the enemy with scars or wounds or even just juice dripping. Seeing the juice on hit is a already very good start :P
Overall, I feel like the game is very fun and interactive, with the shop system in place I feel like I could play endlessly. Continue like that!
