Thank you very much for taking the time to play my game and leave a detailed comment! Yes, unfortunately, I realized too late how harsh my game is on the player, and I will fix this in the future by adding checkpoints/safety zones, coyote time on trap activation, and artifacts to ease gameplay. The mouse aiming feature was added at the last minute at a friend's suggestion, so I didn’t have enough time to fully test its functionality.
As I understand it, the main problems arise from the lack of smoothing during aiming and moving the cursor in fixed update rather than in every frame. To continue the game, clicking is not necessary; just pressing a button is enough. But because I kept pressing buttons, I didn’t manage to see the screen myself, so it forcibly remains active for about a second. I will revisit my solution and may find a more optimal one. Thank you very much for your comment!
