Wow, this one is fully featured! I wasn't expecting much past the first maze level, but it kept going for a while. Some big Montezuma's Revenge vibes with the overall gameplay, which is a thumbs up from me.
The first maze level was enjoyable to explore since things weren't too interlocked, making it easy to find one's way back to wherever else wasn't explored. The levels got more linear over time, which is fine since the actual platforming was strong.
The music was also great! Definitely an unexpected treat, especially with the boss music. Speaking of, the bosses were a good fight even if the challenge was mostly in the vein of just trying to keep on top of them as long as possible. Their jumps sometimes hurt you or sometimes they just take a bunch of hits in a row, so it was a bit of a crapshoot, but it was never frustrating.
Levels introduced new mechanics at a regular pace so things were always interesting, though there are some parts like the player-chasing projectile in a room full of on/off lasers that felt like it was inevitable to take a hit. Otherwise the challenge always felt pretty fair, especially with the generous amount of health.
Good stuff all around!
