Nice to see games made with Unreal engine for this jam! I really appreciated the neat tutorial instructions as part of the gameplay. Also, sound effects are appropriate and everything runs and plays quite smoothly on my machine.
I think the enemy AI could be improved - I managed to kill the enemy by shooting him on the back without him realising that he was being shot - and I would have preferred to find more use for the stealth mode. But overall it's a very good start! Well done!
