This concept is old. The game itself is not very rewarding. I mean 750 is possible, yeah sure, but what for. It's not like that I will be able to save any cuties or doing some super cool tricks. For instance, there could be a character unlocked at a certain score, and cutscene of he/she/it joining and blablablah stuff like that, sweet! Speaking of characters, the ones here are extremely bland and generic. Additionally, there are a lot of great features for one-button games like this one. For example the jump height, it seems to be fixed which is not too exciting to play along. Others possibilities include bonus button rhytm/combination, streak, interacting traps (which honestly I don't expect though because I believe this game is all about killing traps). Also the physics is bad imo and the control feels clunky. In the end, I must admit it's not fair of me saying all this when trying to be constructive. Best of luck with your future work.
