I played through some more of your game and got stuck at 3-3. It's very fun and I am enjoying the variety of content in the later areas, but I seem to be encountering bugs more frequently.
Here's a list of bugs I encountered along the way:
- The collision box for ladders is a bit wider than it should be; this is apparent in 2-1 where you can jump off the side of the ladder to get into the secret path the wrong way.
- You get stuck inside a wall if you walk past the exit in 2-5.
- The second boss still does damage during its death animation. I died to this because I was in the middle of the screen.
- When you open the menu on a screen with grappling points, you can see arcs display on top of the menu.
- There is no option to set a custom control for grappling.
- I found two treasure chests in 3-1 despite the level info saying that there is only one chest in the level.
- There is a treasure chest in 3-3 that requires you to grapple across a lava pit that cannot be opened.
- A little ways past the locked door in 3-3 is a screen that appears to be impossible because of a single block being in the way of a jump that must be made at the bottom of the screen.
- After purchasing the health upgrade, I would die even though I still had half a heart of life remaining.
