The drill being charged needed a bigger visual cue. It took me awhile to even notice what appears to be a slight increase in the drill's shaking, and I never got the timing down right. This got even harder to track during the second phase.
I liked combat for the most part, only going under the mech felt unfair as there was no way to judge and avoid those clustered projectiles in time. Thankfully, I was able to beat the mech by never ever trying to pass under it.
The potatoes were a little confusing. In my first few tries I kept trying to pick them up and assumed them to be connected to health or another character attribute. Thankfully, they're easy enough to tune out amongst the flying projectiles. The art overall is very well done.
Very good job!
