Thanks for the review.
Yea. We thought the same during development. Sadly, I ran out of time doing all the graphics. There's some sound effects when you hit enemies but there's lots of potential for better audiovisual cues.
We had to cut a lot of corners in the end. One level and most of the intro had to be sacrificed to deliver on time.
There's about 60 sound effects that have been recorded but not implemented yet and we had a last-minute merge conflict that appears to have accidentally disabled some button sounds.
