thanks for playing and the feedback. 20 minutes is a long time, can you be more specific about that feeling of lack of progress? like didn't get past a specific wave? or something else? You are right we could have gotten better art I planned on doing better drawings but ran out of time trying to bug fix and we spend longer than we probably should have adding features/ upgrades. (well I probably should have better prioritized the art, and spent more time on weekends working on the art)
