Thanks! Yeah, it's shame that I only made one level, but I wanted to stay within at least somewhat reasonable development time since I make these games as a challenge of sorts (I already went a bit over what was planned).
I made the classic mistake of spending too much time tinkering with code rather than actually making the game, so I'll avoid doing that in the future.
I'll most likely move on to a bigger project soon, so no plans for new levels yet :(. However, I may try and remake it in a month or two, so hopefully I will make it bigger and better that time.
Again, thank you very much for spending time to play it through and comment! I really appreciate it! :)
