Quite an interesting take on the count down theme! I like the optimization aspect of the game, trying to use as little key strokes as possible in order beat a level (kind of like optimizing A-presses which are always interesting to see). I also appreciate that there is a level editor and a way to make community-driven maps, doing this in a game jam is quite impressive
The gameplay is quite simple but a fun gimmick. I think a larger variety of objects will open a lot of potential since currently there is only the bumper object to consider. Having more objects means that optimization of levels becomes more fun! Overall quite fun.
