Really enjoyable game! Almost feels complete with the exception of the short amount of levels. Level design is definitely where this game shines. The final level was a great culmination of the different mechanics introduced throughout the earlier levels, and they're all very creative. Love the steam mechanic and especially using it as both an ascend mechanic and as an obstacle when falling into it from above.
The art style is really consistent and looks excellent. I feel that a tile set would really glue it all together. Audio was very basic and a song for the gameplay would be great.
Perhaps a small thing, but the ending scene was very nice with a lovely piano piece! Overall excellent work on this game. Looking forward to more Lighthouse Studios creations.
