unfortunatly I seem to be a victim of the spawning bug too (web version). However, its a game jam and these things happen and you provided other platforms, so I dont want to penalise you for it (and will try my best to extrapolate from what i was able to play :) )
I liked the vibe, it was fun and a little silly (in a good way), which suited being an animated pencil! The sfx and music fit nicely and everything worked together. I appreciated having instructions on how to do everthing (can be rare in game jams 😅) especially as you had to cater for mobile users too!
EDIT!
I managed to get it working without the bug! I think it might have to do with playing the web build in full screen mode? I restarted and didnt fullscreen and the platforms all spawned much more nicely!
Im glad i got this to work because even when it wasnt it was obvious some work had gone into it, there are lots of nice little touches (the way the penciel moves and shakes) and i could see the vision even when i couldnt get it to work.
With the working version i got into the 50s i think! which, there is a speed up around 30 which is killer. Its got that high score element to it where you think 'ahh if i just try again im sure i can beat that!'. I would in the future love to see my high score on the game over page as i was often so focused on doging and weaving i want paying attention to what score i was on and then would die and not know.
Great job, sorry you've been effected by the curse of the web build! but im really glad you submitted because that was fun!
