Great game, really! I see a lot of potential in it. It's fun, very pleasant to the eye, and kinda addicting, just like a proper Android (or any, actually) game should be.
The levels are simple and quick, but there's a lot of them, so they keep a player entertained for long.
Let me point out some things to improve/consider:
- Slight glitch - the cowboy starts flashing if you restart while getting electrocuted. While the sprite is off, you can't shoot.
- Starting from level 42, the level number gets offset by 1. Level 42 is shown as 43, 43 is shown as 44.
- I got 3 stars for every level but didn't get the achievement!
- At first, I didn't know the tutorial was a separate level. Started with level 1, thinking it would be a tutorial.
- How about a "yeee ha" instead of kids crowd as a level finish sound?
- Add a "back to main menu" button in level select menu
- I wonder about the portals. I knew I should go for them, because I saw your update about it on Discord, but they might not be very visible to someone who doesn't know about them. Also, I think you could add some particles on teleport, and definitely a sound effect.
- The music lags a bit during level scene changing
- I didn't think the game was really hard. It was "just fine" in terms of difficulty. The only level I had a lot of difficulties with, was 34. I'm only saying this, so you can keep that in mind, if you do decide to lower the difficulty, based on the feedback.
