I played this last night, but was incredibly tired and totally blanked on leaving a comment!
This was a really cool game. I loved the low-poly PS1-ish aesthetic. It really came together nicely. I was very impressed with the variety of gameplay. Exploring was cool, and the battle segments were fun and engaging.
I did find the controls a little tough a times (the exploration part took a minute to get used to on the train) but that also felt PS1 authentic.
Battling was good, but I did find it strangely difficult to hit the eyeball enemies with the wand attack. It often felt like my shots just went right through them. I almost gave up, but scraped by on my 3rd attempt.
The train section on the other hand, was a lot easier, though I did initially leap off the train XD
Overall this was a very impressive game, great work!
