Wow, what a bombshell to end on.
Fun game, I think I collected all the upgrades (100+100) and the ramp up feels satisfying and gives a nice sense of speed. The ones in mid-air were a little hard to collect once you already have a few upgrades so it would be nice if they had a bigger hitbox or they were drawn to the player a little.
The woods definitely didn't remind me of any 1998 action-adventure games developed and published by Nintendo for the Nintendo 64 but I really liked how you solved the issue of players falling down the holes there.
The 3D models are really nice, I like the cow one. I felt bad when I accidentally ran into one.
