This is a great and short metroidvania!
Graphics is amazing, it has this hand draw aspect to it that really stands out.
Gameplay is absolutely as basic as possible for metroidvania, but works really well. Movement is fluid and snappy!
What really bothered me was how linear it was but in the end, it didn't really detract from the good experience I had while playing.
Highly recommend for a quick and well done metroidvania!
