Stumbled upon it, For $4 CAD, This game has more value then games that cost $20-30 in it's genre. It's very polished and complete. The Mechanics are simple yet engaging. I'll be digging in more and watching this game develop. I like the Graphics of the main char a lot, the enemies could use more variety which likely will come in time. Levels are all alike, could use some more variety. The Melee and gunplay are satisfying. Cool Upgrade system, I'm very surprised of the cost for it. I'll be spending hours on it this weekend. I could be playing any other game in my library but the $4 hidden gem is a blast.8 found this helpful
For an early access game this shows a lot of promises. Quite a few bugs that def need to be worked out but overall great concept for a game. Can't wait to see the finished project! Full summary of the game here: https://www.youtube.com/watch?v=O2j_yuBCdl41 found this helpful
