Well... I couldn't find a way to complete the game, if there was an ending... Judging by the screenshot below the game, there is?
Anyways... I kind of don't get the game... What are the colored bottles for? I don't see any difference between two colors - except the color?
The jump is also a hit and miss... It is floaty, and then sometimes the character seems to get stuck on the ledges.
The camera is quite close - and the enemies get you in one hit, often you having no time to react & end up just spamming bullets as you walk forward. This might use some balancing.
I'd like to see this game when you guys implement the features you wanted... so good luck, and thanks for sharing the game!
