Hello,
This game is pretty fun to play and looks appealing. The mechanics so far integrated into the Game are quite decent and well thought, improving the puzzles ahead with these mechanics could make this game rank higher for sure. However, a few things that needed to be taken care of to spice up the feel and maintain the game flow are -
1. The Play Button on Start seems to be not responsive sometimes, for example, when you hit Play Button for the first time, it's not actually doing anything but if you start to hit twice, thrice or more than that, it seems to stick and never go ahead. If you are loading the game at this point then make sure to indicate to the player that the game is loading and disable the Play Button at least.
2. When reaching the door the Game automatically finishes the level, this seems a little off and unnatural, so all you can do is to touch a specific point or have one indicator like led light or something that glows when a player is near the end door to give slight feedback to the player what's going on in the Game.
3. On Level 2 when it instructs the Player to Spawn another E-Bot, you need to restrict the number of E-Bot, or else Users can hit the S button 100 times and see their game and laptop both crashing. Also, It's better to instruct the Player when it's needed, so you can instruct the User to hit S Button to Spawn a new character when the old one is stuck inside the hole.
4. Adding Camera Shake and Particle Effect on Blast would give more natural impact to the Users and would be satisfying too.
So, here were a few points you can improve upon. Let us know if it helps and keep updating the game with more new exciting levels. If you need any Game Dev Resources for Free, check out our Store and Grab all you like.
