I absolutely agree with you on all of your points!, the feedback for hitting enemy is quite nonexistent (yeah we didnt even think about it). and the teleportation is not immediately useful.
We were planning to make an upgradeable weapon /teleport range, but ran out of time before we were able to do that so we just decided to upgrade the teleportation range the lower your level is
Thank you so much for your feedback, we hope you enjoy our game! 😁
