Thank you very much for playing the game and thank you very much for the feedback man! I had a feeling that it might have been my hardware which was causing the mouse issue but I guess not. I'll be looking into this for sure.
Cool idea, though for some reason the square on my end wouldn't fall through the gaps or would just have its y-position incrementing with each jump. (This was present in the web version, I'm using Edge, Hardware Acceleration is off)
Thank you for the feedback, I actually tried to make this game using a new framework I created and along the way I noticed a lot of things that could be improved with the engine and the game. I am going to definitely be updating this game later on as well, would you like to be notified?
