Thanks a bunch for the feedback and great to hear you enjoyed the game.
Yes, the camera, it was perhaps ill-advised to unintentionally induce sea sickness, regardless of how thematically appropriate it might be. This issue unfortunately flew by us while focusing on implementing other aspects, we will 110% get this fixed looking forward - and we are keen to look forward.
The shop was another causality of neglect while racing towards the deadline. You are very much on point, there is currently zero feedback in the store when making purchases. We actually have a sound effect ready within the game project already, however slipped by us in having it rigged up before the deadline. That sound effect was the intended bare minimum feedback for making a purchase, a hefty "Ka-ching" sound. Another intended change I intentionally skipped making due to limited time, was to adjust the whole store screen UI to better reflect the current upgrade stats and quantity of abilities held within the store menu itself, rather than only being visible on the distant screen UI. There is that and the store is missing an option to simply press a "back" button to quickly exit rather than scrolling down the click "exit".
Thanks a bunch for the compliment on the characters and animations, I very much appreciate hearing it. The intent behind the designs was to try to create something visually distinct and whacky, to fit with the crazy premise, great to hear it landed well! 😁 I set myself the goal of creating all the art in the game from scratch, from modeling, texturing, rigging and making the characters modular by design for possibility of variants (only 2 made it in time). Only the animations needed a little help from Mixamo to get base animations in place, save a bit of time and rather spend time altering them and editing as needed, some squash & stretch methods (build animation being the clearest example).
