Hey there - tbh, I haven't played anything like this so far - just pointing that out of the gate. I did 1 run, it was pretty chill, relaxing even - until I decided to throw something off to the bottom right of the board(which resulted in the endgame screen)
What I'm missing is some sort of pressure for this to click and make me want to do consecutive runs(just my personal take, if your idea is to have a chill experience in-game, don't think too much of it). I think this answers question 1; about question 2 - honestly, aiming and launching felt satisfying and precise - I had to switch to fullscreen for this to apply though. I hope this helps you in any way - good luck with the project and most importantly - have fun building it
