Honestly a very very polished game, I would not have expected this was made by one person in 2-4 days without premade assets. It's a very simple concept, but I can see how complex this game can get. I only managed to get to level 3 before dying immediately but I really have no big complaints with this game. I think the only nitpick I have is that there was no music, but the sound design even without music felt really satisfying.
Overall, I really enjoyed this game :>
