This is just really cool! All the pixel art is really pretty and well made, very clear to read too! UI is so unbelievably clean and such a nice fade transition! Really awesome idea for the gameplay and it is quite fun to consider setups for different traps. I do think the pacing is a bit off in the upgrades maybe, at least in order to get the most points, ideally you want to save the upgrades that do multipliers once you've got all the addition upgrades but then the moment you get one multiplier the difficulty ramps up by a huge amount, maybe that's not an issue and I just need to get better lol, still made it onto the leaderboard at least! A real big shame you didn't do music but seeing that you chose to focus on the leaderboard instead was a very smart move, I think it payed off perfectly because my first playthrough I died and didn't get onto the leaderboard, I went again to try and get on! (and thankfully succeeded). This really slaps and you definitely cooked something here, you could easily expand on this game, love the little story at the start, the art for the robot character looked sick and dialogue worked fine and in a satisfying way! Every aspect of this game really slaps (apart from lack of music lol but the sfx were good), excellent work!
