Made in 15 hours is impressive! It was fun and the artstyle was great. In terms of feedback:
Fun: yes for some reason it made me think of a golfcourse made it kinda puzzle like for me
core elements: some elements I did miss just a simple kill all enemies advance wouldve done wonders but I do feel like it counts as a recreate
Polished: Its good, i did encounter some minor bugs like body parts getting stuck or already being killed without even being picked up, but besides that movement and controls were good
Sound fx: really sad you didnt do anything for this :/
UI: its great, simple yet effective
Great job!
