That cut scene was simple at the start but really does so much to drive and motivate a player which I think I stand out considering it could have easily just been game with a score and nothing else to entice the gameplay.
The fact that as you went higher and higher new objects were being added also gave a really clear promt to the player that they were progressing without telling them or using UI, while i never made it too the top because the RNG gods hate me and everything i do in life i will say because of all the effort you put into this game i wanted to kick that alien in the face.
Some life drop also would have been nice since the game can be quite tough at times.
Overall a amazing story was conveyed to the player with such few assets which i think is incredible.
